Personal Endings. Personal endings are attached only to finite verbs (“[with] endings”), as opposed to infinitives (“[with] no endings”). Latin verb endings denote person (first/second/third) and number (singular/plural).

The personal endings in the passive voice (present, imperfect, future) are: -r, -ris, -tur, -mur, -mini, -ntur.

The endings by means of which a verb indicates person and number are called personal endings. In the present tense a verb has two personal endings,…. EST for the second person singular and S for the third person singular (old form eth).

A Complementary Infinitive is used to extend and fill out the meaning of a verb which would have a very limited meaning without the infinitive.

The subjunctive mood is for uncertainty, often expressing as a wish, desire, doubt or hope as in: “I wish I were sleepy.”

MOOD: Latin has four Moods: Indicative, Subjunctive, Imperative, Infinitive.

These can be: I (first person); you (the second person singular); he, she, it (a third-person singular person removed from the conversation); we (first person singular); all of you (second person plural); or they (third person plural).

Body. Every verb in Latin has mood, that is, it expresses a certain modality of action. There are three moods for the Latin verb, not including the infinitive, which does not have mood or person or number (hence, its name which means “not defined”: in = not, finite = defined).

Alongside the perfect and imperfect tenses, a further past tense exists in Latin. This is called the pluperfect tense. The pluperfect tense (or past perfect in English) is used to describe finished actions that have been completed at a definite point in time in the past.

English. In English grammar, the pluperfect is formed by combining the auxiliary verb had with the past participle of the main verb, as in had jumped or had written. English also has a past perfect progressive (or past perfect continuous) construction, such as had been working.
