firmi

Firmi is the second-person singular present indicative form of the Italian verb firmare, meaning to sign. It is used when addressing someone informally in the present tense, as in Tu firmi un contratto ogni volta che lo desideri.

Etymology and related forms: firmare derives from Latin firmare, from firmus meaning firm or secure. The verb belongs to the first-conjugation class (-are). The present-tense paradigm for firmare is: io firmo, tu firmi, lui/lei firma, noi firmiamo, voi firmate, loro firmano. The formal address using Lei uses the third-person singular, as in Lei firma. The imperative forms are firma (informal singular) and firme (formal or plural, depending on construction). The noun firma means signature.

Grammar and usage notes: firmi appears in statements directed at a familiar second person in the present tense. It can appear in questions or in subordinate clauses with verbs of speaking, thinking, or deciding, for example: È importante che tu firmi il documento. In negative or interrogative forms, it follows standard Italian syntax, for instance: Tu non firmi senza controllare i dettagli.

Examples: Tu firmi il contratto, vero?; Per favore, firma qui. Lei firma domani; Vuoi che ti firmi questa lettera?
