Articles and adjectives must agree in case, number and gender with the nouns they modify. Sample Latin verb: the present indicative active of portare (portar), to carry: porto - I carry portas - you [singular] carry portat - he carries portamus - we carry portatis - you [plural] carry portant - they carry In Latin, a pronoun such as "ego" and "tu" is only inserted for contrast and selection. Proper nouns and common nouns functioning as subject are nonetheless frequent. For this reason, Latin is described as a null-subject language. French Spoken French always distinguishes the second person plural, and the first person plural in formal speech, from each other and from the rest of the present tense in all verbs in the first conjugation (infinitives in -er) other than aller. The first person plural form and pronoun (nous) are now usually replaced by the pronoun on (literally: "one") and a third person singular verb form in Modern French. Thus, nous travaillons (formal) becomes on travaille. In most verbs from the other conjugations, each person in the plural can be distinguished among themselves and from the singular forms, again, when using the traditional first person plural. The other endings that appear in written French (i.e.: all singular endings, and also the third person plural of verbs other than those with infinitives in -er) are often pronounced the same, except in liaison contexts. Irregular verbs such as être, faire, aller, and avoir possess more distinctly pronounced agreement forms than regular verbs. An example of this is the verb travailler, which goes as follows (the single words in italic type are pronounced /tʁa.vaj/): je travaille tu travailles il travaille nous travaillons, or on travaille vous travaillez ils travaillent On the other hand, a verb like partir has (the single words in italic type are pronounced /paʁ/): je pars tu pars il part nous partons, or on part vous partez ils partent The final S or T is silent, and the other three forms sound different from one another and from the singular forms. Adjectives agree in gender and number with the nouns that they modify in French. As with verbs, the agreements are sometimes only shown in spelling since forms that are written with different agreement suffixes are sometimes pronounced the same (e.g. joli, jolie); although in many cases the final consonant is pronounced in feminine forms, but silent in masculine forms
