otherwise common phonetic rules switch their pronunciations. T–V distinction Italian makes use of the T–V distinction in second-person address. The second-person nominative pronoun is tu for informal use, and for formal use, the third-person form Lei has been used since the Renaissance. It is used like "Sie" in German, "usted" in Spanish, and "vous" in French. Lei was originally an object form of ella, which in turn referred to an honorific of the feminine gender such as la magnificenza tua/vostra ("Your Magnificence") or Vossignoria ("Your Lordship"), and by analogy, Loro came to be used as the formal plural. Previously, and in some Italian regions today (e.g. Campania), voi was used as the formal singular, like French "vous". The pronouns lei (third-person singular), Lei (formal second-person singular), loro (third-person plural), and Loro (formal second-person plural) are pronounced the same but written as shown, and formal Lei and Loro take third-person conjugations. Formal Lei is invariable for gender (always feminine), but adjectives that modify it are not: one would say to a man La conosco ("I know you") but Lei è alto ("You are tall"). Formal Loro is variable for gender: Li conosco ("I know you [masc. pl.]") vs. Le conosco ("I know you [fem. pl.]"), etc. The formal plural is very rarely used in modern Italian; the unmarked form is widely used instead. For example: Gino, Lei è un bravo ingegnere. Marco, Lei è un bravo architetto. Insieme, voi sarete una gran bella squadra. ("Gino, you are a good engineer. Marco, you are a good architect. Together, you will make a very good team."). Verbs Based on the ending of their infiniti presenti (-are, -ere, or -ire), all Italian verbs can be assigned to three distinct conjugation patterns. Exceptions are found: fare "to do/make" (from Latin FACĔRE) and dire "to say" (from Latin DICĔRE) were originally 2nd conjugation verbs that reduced the unstressed vowel in the infinitive (and consequentially in the future and conditional, whose stem derives from the infinitive), but still follow the 2nd conjugation for all the other tenses; this behaviour is similarly featured in the verbs ending in -trarre, -porre and -durre, derived respectively from the Latin TRAHĔRE (to drag), PONĔRE (to put) and DVCĔRE (to lead). Just like many other Romance languages, Italian verbs express distinct verbal aspects by means of analytic structures such as periphrases, rather than synthetic ones; the only aspectual distinction between two synthetic
