=== Defective verbs ===
[[Defective verbs]] are verbs that are conjugated in only some instances.
*Some verbs are conjugated only in the perfective aspect's tenses, yet have the imperfective aspect's tenses' meanings. As such, the perfect becomes the present, the pluperfect becomes the imperfect, and the future perfect becomes the future. Therefore, the defective verb ''ōdī'' means, "I hate." These defective verbs' principal parts are given in vocabulary with the indicative perfect in the first person and the perfect active infinitive. Some examples are:

::{{lang|la|ōdī, ōdisse}} (future participle {{lang|la|ōsūrus}}) – to hate
::{{lang|la|meminī, meminisse}} (imperative {{lang|la|mementō, mementōte}}) – to remember
::{{lang|la|coepī, coeptum, coepisse}} – to have begun
*A few verbs, the meanings of which usually have to do with speech, appear only in certain occurrences.

::{{lang|la|Cedo}} (plur. {{lang|la|cette}}), which means "Hand it over" is only in the imperative mood, and only is used in the second person.

The Romance languages lost many of these verbs, but others (such as {{lang|la|ōdī}}) survived but became regular fully conjugated verbs (in Italian, {{lang|it|odiare}}).
