This case, originally a single-judge appeal pursuant to sec. 752.31(2)(f), Stats., was ordered to be heard and decided by a panel because of the importance of the issue raised: whether trial courts have the authority to order probation for a defendant convicted of driving while intoxicated for the third time in five years in light of sec. 346.65(2) (c), Stats., which provides that such persons “[s]hall be ... imprisoned for not less than 30 days nor more than one year ....” More specifically, the question is whether a condition of probation requiring the defendant to spend thirty days in the county jail (during non-working hours) may be considered “imprisonment” within the meaning of sec. 346.65(2) (c). We answer the question in the negative and therefore reverse the judgment of conviction and *206sentence, remanding the case to the trial court for resentencing.
Michael A. Meddaugh entered a plea of no contest to the charge of operating a motor vehicle while intoxicated contrary to sec. 346.63(1)(a), Stats. It was his third such conviction in five years. In fact, at the time of the offense he was on parole in connection with his conviction and imprisonment for two counts of homicide by intoxicated use of motor vehicle. In light of the seriousness of the present offense and Meddaugh’s prior record, the prosecutor recommended the maximum imprisonment (one year), fine ($2,000) and license revocation (three years). The trial court agreed, stating: “I have concluded [that] I wish to impose the maximum sentence.”
Then, noting Meddaugh’s rehabilitative needs and the inadequacy of a “straight” jail sentence to deal with those needs, the court imposed the maximum one-year jail sentence but stayed it, placing Meddaugh on probation for a period of two years. One of the conditions of probation was that Meddaugh spend thirty days in the Dane County Jail during nonworking hours. The state appealed, claiming that, under the mandatory imprisonment terms of sec. 346.65(2)(c), Stats., and relevant case law, the court lacked authority to enter such an order. Other facts will be referred to below.
We begin with the proposition that probation is ‘“a matter of grace or privilege ...’ made possible by the legislature.” State v. Evans, 77 Wis. 2d 225, 230, 252 N.W.2d 664, 666 (1977) (citations omitted). And because the punishment to be imposed for particular crimes is within the sole province of the legislature, courts have no power to stay or suspend execution of sentences, and instead grant probation, in the absence *207of specific statutory authority. State v. Sittig, 75 Wis. 2d 497, 499-500, 249 N.W.2d 770, 772 (1977). Under sec. 973.09(l)(a), Stats., except for first degree murder or any other offense for which probation is prohibited by statute, courts are authorized to withhold sentencing a defendant — or impose a sentence and stay its execution — and place the person on probation for a stated period, subject to stated conditions. Given the mandatory imprisonment language of sec. 346.65(2)(c), Stats., however, we conclude that courts lack authority to withhold or stay the sentencing of persons convicted of that offense and instead place them on probation.
In State v. Duffy, 54 Wis. 2d 61, 63, 194 N.W.2d 624, 625 (1972), the supreme court considered whether the language of sec. 343.44, Stats. (1969), which, like sec. 346.65(2)(c), Stats., stated that persons convicted of operating a motor vehicle after revocation of their driver’s license “shall be imprisoned” for a specific period of time, precluded “the availability of probation to [persons] convicted thereunder.” In holding that it did, the court noted the distinction between criminal statutes providing penalties which courts “may” impose, and those providing penalties which “shall” be imposed, and stated:
Most of the penal statutes of this state grant the trial court discretion to either impose a sentence of imprisonment within prescribed statutory limitations or to impose a period of probation pursuant to the provisions of sec. 973.09, Stats. This authority is generally indicated by the language “may be imprisoned,” which precedes the limitation on the period of imprisonment in the particular provision. The legislature has enacted but few statutory provisions comparable to the one in the instant case, which expressly provide that a person convicted thereun*208der “shall be imprisoned.” If probation were to be available in either case, the legislature would have no purpose in employing the word “may” in some cases and the word “shall” in others.
We arrive at the inescapable conclusion that the legislature left the trial court with no alternative but to impose a sentence of not less than five days upon a person convicted of a violation of this section of the statutes. Id. at 64-65, 194 N.W.2d at 626. [Footnote omitted.]
In State v. McKenzie, 139 Wis. 2d 171, 175-76, 407 N.W.2d 274, 276 (Ct. App. 1987), we considered the reverse situation — whether the trial court erred in not considering probation in a motor vehicle offense where the statute provided that one convicted of the offense “may be imprisoned not less than 30 days nor more than one year —” (Emphasis in original.) We held that because imprisonment was not mandatory, the trial court erred as a matter of law when it concluded that probation was not available.
The “may/shall” distinctions are still present in the motor vehicle laws. Those persons with prior convictions in the preceding four-year period who are convicted of reckless driving, for example, “may be ... imprisoned not more than one year in county jail, ” whereas drunk driving “repeaters,” such as Meddaugh, u[s]hall be ... imprisoned for not less than 30 days nor more than one year in the county jail _” Secs. 346.65(1) and (2)(c), Stats, (emphasis added). Indeed, the language of the statute the supreme court held in Duffy did not permit probation is identical to the language of the statute under which Meddaugh was convicted.
Meddaugh argues, however, that Duffy is distinguishable because in that case the trial court did not set *209county jail confinement as a condition of the defendant’s probation, as the court did in this case. We are not persuaded. The Duffy court never mentioned the presence or absence of a probationary jail condition as having any bearing on its holding as to the meaning and effect of the mandatory statutory language. The court framed the issue as whether “the provisions of the statute ... preclude the availability of probation to one convicted thereunder,” id., 54 Wis. 2d at 63,194 N.W.2d at 625; and that is the issue the court decided. It was not an issue whose resolution depended upon the particular facts of the case. It was strictly a legal question — what the legislature intended when it used “shall be imprisoned” rather than “may be imprisoned” in the statute. And the court resolved that issue independent of the factual setting in which it arose.
Nor are we persuaded by Meddaugh’s argument that, considerations of probation aside, he was in fact “imprisoned” within the meaning of sec. 346.65(2)(c), Stats., by the confinement condition of his probation. We agree that one of Webster’s definitions of the term “imprison” is “to put in prison: confine in a jail.” And while it may be true that the word is often used in a broad, general sense, “imprison” is also a legal term and, as such, “should be given its legal meaning when used in the statutes and the law unless there are strong indications the term was used in a general sense.” Prue v. State, 63 Wis. 2d 109, 116, 216 N.W.2d 43, 46 (1974).
The issue in Prue was whether a person who is “confined” in the county jail as a condition of probation is serving a “sentence” of imprisonment within the meaning of the laws giving prisoners “good time credit” on their sentences. Id., 63 Wis. 2d at 114, 216 N.W.2d at 45. The court noted first that even though a probation condition of confinement is similar to the “confine*210ment” involved in a sentence of imprisonment, the two are distinct, “alternative” concepts. Id. Then, adopting the “generally accepted” view that probation — even when accompanied by a period of incarceration — is not a sentence, the court held that good time could not be credited against incarceration imposed as a condition of probation because that time was not being served pursuant to any sentence imposed by the court. Id. at 114-16, 216 N.W.2d at 45-46.
When it provided for “imprisonment” of persons convicted of multiple drunk driving offenses in sec. 346.65(2)(c), Stats., the legislature gave no indication that it intended that word as meaning anything other than its accepted legal definition — incarceration pursuant to the imposition of a sentence. Prue, 63 Wis 2d at 115-16, 216 N.W.2d at 46. And when it made imprisonment mandatory upon conviction, the legislature took away from Wisconsin judges a significant part of the discretion that normally attends the sentencing process.
We appreciate not only the trial court’s good intentions and its well-reasoned disposition of the case, but also the fact — as the court noted — that imprisonment without probation would not provide Meddaugh adequate access to rehabilitative services. It has been held, however, that:
The fashioning of a criminal disposition is not an exercise of broad, inherent court powers. It is for the legislature to prescribe the punishment for a particular crime and it is the duty of the court to impose that punishment; if the authority to fashion a particular criminal disposition exists, it must derive from the statutes. State v. Amato, 126 Wis. 2d 212, 216, 376 N.W.2d 75, 77 (Ct. App. 1985) (citations omitted).
*211There can be little doubt that if the trial court had not imposed any jail time as a condition of Meddaugh’s probation, Duffy would require reversal. And the fact that the court set the jail-time condition at thirty days — the minimum term of “imprisonment” under sec. 346.65(2)(c), Stats. — does not change that result because, as the court held in Prue, whatever its terms and whatever its conditions, probation is not a sentence of imprisonment.
Were we free to make our own laws, we would undoubtedly authorize and approve the trial court’s actions in this case, as the dissent has done. But we are law interpreters, not lawmakers, and we believe that reading Prue, Duffy, and sec. 346.65(2)(c), Stats., to permit suspension of the mandatory jail sentence and substitution of a term of probation would cross that line. We also believe that the Prue court’s dictum reference to the desirability of trial court “leeway” in setting the terms of probation does not change that court’s explicit recognition of the principle that probation — whether or not accompanied by a jail-time condition — “is ... not a sentence....” Prue, 63 Wis 2d at 114, 216 N.W.2d at 45.
We see no “irony” in our decision, and we disagree most strongly with the dissent’s ad populum argument that our decision, even though it follows the mandate of the applicable statutes and cases, somehow results in more lenient treatment of drunk drivers than the legislature could have intended.
Probation is, by definition, an alternative to punishment, to be imposed when the trial court determines that the defendant should not be punished as the law otherwise would require. In the most severe view, it is a “mode of mild and ambulatory punishment... intend*212ed as a reforming discipline.” Toyosaburo Korematsu v. United States, 319 U.S. 432, 435 (1943) (citation omitted). And while it may be considered as “punishment” for purposes of a double jeopardy analysis, State v. Dean, 111 Wis. 2d 361, 365-66, 330 N.W.2d 630, 632-33 (Ct. App. 1983), it is not punishment in the commonly-understood meaning of the word.
The word “probation” derives from the Latin “to prove,” and the legal sanction is designed to permit the offender to “prove” himself or herself without being punished — to foster rehabilitation and to “help the probationer become a useful member of society.” Wagner v. State, 89 Wis. 2d 70, 77, 277 N.W.2d 849, 852 (1979). It is imposed in circumstances where “the court has determined from the defendant’s character and the circumstances of the case that the defendant is not likely again to commit crime and that the public welfare does not require that he [or she] shall suffer the penalty of the law.” State v. Scherr, 9 Wis. 2d 418, 423, 101 N.W.2d 77, 80 (1960). The dissent’s assertion that the legislature must have felt that probation with a jail condition — which, of course, can be shortened or forgiven at any time — “would punish and deter drunk drivers more than jail alone” is incompatible not only with the Prue court’s holding that imposition of a period of confinement does not change the alternative, nonpenal remedy of probation into something it is not, but it also runs contrary to the historic, universally-recognized purposes and uses of probation as a remedy in the criminal court system.
Unlike the dissenting judge, we do not see a mandatory jail sentence as a more lenient sanction than probation — even where that probation is accompanied, as in this case, by a brief period of confinement in the *213county jail. To the contrary, it is equally, if not more reasonable, to assume that the legislature’s rare use of a mandatory jail sentence — without the discretion to allow substitution of alternative, nonpenal remedies— would reflect that body’s concern over the very, very serious problems caused by intoxicated drivers on Wisconsin’s highways and its belief that repeat offenders, having already had the opportunity to “prove” themselves and having failed at the task, should be imprisoned. Period.
Finally, even though the trial court indicated in its remarks at the sentencing hearing that it felt Med-daugh deserved maximum penalties, and even though it did impose (and then stayed) the maximum one-year sentence, we do not agree with the state’s argument that we should simply modify the judgment to impose that sentence and vacate the probation terms. Despite the court’s remarks, it considered a variety of factors in attempting to fashion what it believed to be a remedy consistent with both the state’s and the defendant’s interests. Unfortunately, our own interpretation of the applicable statutes and cases has rendered that attempt a nullity, and we believe the trial court should have the opportunity to resentence Meddaugh under what we here declare to be the applicable legal principles.
By the Court. — Judgment reversed and cause remanded for further proceedings consistent with this opinion.
