Cupiō means “desire,” “long for,” “wish,” or “be eager.” Its principal parts are cupiō, cupere, cupīvī, cupītum. Although the first form ends in -iō, the infinitive cupere identifies a third-conjugation -iō verb, not a fourth-conjugation verb. Its present system therefore combines third-conjugation endings with an i in forms such as cupiō, cupiunt, and cupiēbam.
The object desired is accusative. An infinitive expresses a desired action; if the desired action has a different subject, that subject is accusative. English often uses “want,” but cupiō normally suggests positive desire or eagerness and is frequently stronger than neutral volō “be willing, want.”

While we were at Rome, we longed for peace.
Post tantum labōrem quiētem cupiēs.
After so much work, you will want rest.
Semper cupīvī Graeciam vidēre.
I have always wanted to see Greece.
The imperfect depicts a continuing desire, while the perfect views the desire as a bounded past state or as one extending up to a reference point. Classical authors also use contracted perfect forms such as cupiī, cupīstī, cupieram, cupīsse beside the transparent forms in -īv-.

| Present | cupiam | cupiās | cupiat | cupiāmus | cupiātis | cupiant |

| Perfect | cupīverim | cupīverīs | cupīverit | cupīverīmus | cupīverītis | cupīverint |
| Pluperfect | cupīvissem | cupīvissēs | cupīvisset | cupīvissēmus | cupīvissētis | cupīvissent |
Quid cupiās apertē dīc.
Say openly what you want.
Sī honōrēs nōn cupīvisset, līberius locūtus esset.
If he had not desired public honors, he would have spoken more freely.
The form cupiam can be future indicative “I shall desire” or present subjunctive “I may desire.” In nesciō quid cupiam “I do not know what I want,” the indirect question requires the subjunctive.
Passive System and Its Limits
The passive is morphologically regular, but it is much less frequent than the active because desiring naturally foregrounds the experiencer. It is most plausible when a person, office, outcome, or possession is said to be desired.
| Tense or mood | 1st sg. | 2nd sg. | 3rd sg. | 1st pl. | 2nd pl. | 3rd pl. |
|---|---|---|---|---|---|---|
| Present indicative | cupior | cuperis | cupitur | cupimur | cupiminī | cupiuntur |
| Imperfect indicative | cupiēbar | cupiēbāris | cupiēbātur | cupiēbāmur | cupiēbāminī | cupiēbantur |
| Future indicative | cupiar | cupiēris | cupiētur | cupiēmur | cupiēminī | cupientur |
| Present subjunctive | cupiar | cupiāris | cupiātur | cupiāmur | cupiāminī | cupiantur |
| Imperfect subjunctive | cuperer | cuperēris | cuperētur | cuperēmur | cuperēminī | cuperentur |
Perfect-system passives use cupītus, -a, -um plus sum: cupītus est perfect, cupītus erat pluperfect, cupītus erit future perfect, cupītus sit perfect subjunctive, and cupītus esset pluperfect subjunctive. These are valid but relatively uncommon; a table should not imply equal frequency merely because the forms are possible.
Pāx ab omnibus cupitur.
Peace is desired by everyone.
Ille honōs ā multīs cupītus erat.
That office had been desired by many.
Commands and Non-Finite Forms
The present active imperatives are cupe, cupite. Direct commands to desire something are unusual in ordinary communication, though exhortations can make them meaningful. Passive commands cupere, cupiminī and future imperatives cupitō, cupitōte, cupiuntō are (formal/archaic) and extremely rare.
| Category | Active | Passive |
|---|---|---|
| Present infinitive | cupere | cupī |
| Perfect infinitive | cupīvisse / cupīsse | cupītum esse |
| Future infinitive | cupītūrum esse | cupītum īrī (rare/formal) |
| Participles | cupiēns; cupītūrus | cupītus; cupiendus |
| Gerund | cupiendī, cupiendō, cupiendum, cupiendō | — |
| Supines | cupītum, cupītū | — |
Dīcit sē nihil praeter pācem cupere.
He says that he desires nothing except peace.
Vir glōriam cupiēns omnia perīcula subiit.
The man, desiring glory, faced every danger.
Bona mentis magis quam dīvitiae cupienda sunt.
Goods of the mind should be desired more than riches.
The gerundive here expresses what ought to be desired and so has an evaluative force. The future passive infinitive cupītum īrī is theoretically regular but (rare/formal) and generally replaced by clearer phrasing.
Noun and Infinitive Complements
With a noun, cupiō takes a direct accusative: pācem cupiō, honōrēs cupit. English “desire for” may tempt learners to add a preposition, but Latin’s verb is transitive.
When the subject of cupiō also performs the desired action, a plain infinitive is normal: domum redīre cupiō “I want to return home.” When another person is to perform it, that person stands in the accusative with an infinitive: tē venīre cupiō “I want you to come.” English expresses this with “you” rather than “you to” after some verbs, so the Latin structure should be parsed independently.
Cupimus tē nōbīscum manēre.
We want you to stay with us.
Senātōrēs cōnsulem rem pūblicam dēfendere cupiēbant.
The senators wanted the consul to defend the state.
Negation normally falls on what is not desired: nōn cupiō “I do not desire.” If the meaning is positive unwillingness or refusal, nōlō may be more exact than a mechanically negated cupiō.
Cupiō, Volō, and Desire
Volō ranges broadly from wanting to being willing or intending. Cupiō emphasizes appetite, eagerness, or longing. Thus venīre volō can simply state an intention to come, while venīre cupiō highlights desire. The distinction is not absolute: genre, emphasis, and object matter, and English “want” can translate either.
The volō reference page gives the suppletive forms and broader syntax of that more neutral verb of wanting and willingness.
The noun cupiditās denotes desire, often intense or blameworthy according to context; cupidus means desirous and commonly takes a genitive. Do not transfer that adjective’s genitive government back to the verb cupiō.
Compounds and Derivatives
Percupiō, percupere, percupīvī, percupītum strengthens the meaning to “desire greatly.” Concupīscō is an inchoative or intensified family member, “begin to desire, covet”; it has a different present-system shape and becomes especially prominent in later and Christian Latin (later/religious). These meanings are lexical: a prefix can strengthen or reshape the desire, but the resulting verb’s full principal parts must still be checked.
Percupiō scīre quid acciderit.
I am extremely eager to know what happened.
Parsing Diagnostic
With cupi- / cupe-, identify the third-conjugation -iō present system from the ending: cupit present, cupiēbat imperfect, cupiam future or subjunctive, cuperet imperfect subjunctive. Cupīv- marks the full perfect active, while cupīt- supplies participial and other supine-based forms. Then locate an accusative noun or infinitive complement and identify who performs the desired action.
Common Mistakes
Treating cupiō as a regular fourth-conjugation verb
❌ Pācem cupīmus.
Incorrect — the present plural has short i: cupimus.
✅ Pācem cupimus.
We desire peace.
Adding a preposition before the thing desired
❌ Cīvēs ad pācem cupiunt.
Incorrect — cupiō takes a direct accusative object.
✅ Cīvēs pācem cupiunt.
The citizens desire peace.
Leaving a different infinitive subject nominative
❌ Cupiō tū venīre.
Incorrect — the subject of the infinitive must be accusative.
✅ Cupiō tē venīre.
I want you to come.
Inventing a present from the perfect stem
❌ Puer domum cupīvit redīre nunc.
Incorrect for present time — cupīvit is perfect, ‘desired.’
✅ Puer domum redīre nunc cupit.
The boy now wants to return home.

- Use an accusative noun for the desired object and an infinitive for the desired action.
- A different subject of the infinitive is accusative: tē venīre cupiō.
- Passive forms exist but are substantially less common than active expressions of desire.
