A peculiarity of Venetian grammar is a "semi-analytical" verbal flexion, with a compulsory "clitic subject pronoun" before the verb in many sentences, "echoing" the subject as an ending or a weak pronoun. Independent/emphatic pronouns (e.g. ti), on the contrary, are optional. The clitic subject pronoun (te, el/la, i/le) is used with the 2nd and 3rd person singular, and with the 3rd person plural. This feature may have arisen as a compensation for the fact that the 2nd- and 3rd-person inflections for most verbs, which are still distinct in Italian and many other Romance languages, are identical in Venetian. (The Piedmontese language also has clitic subject pronouns, but the rules are somewhat different.) The function of clitics is particularly visible in long sentences, which do not always have clear intonational breaks to easily tell apart vocative and imperative in sharp commands from exclamations with "shouted indicative". In Venetian the clitic el marks the indicative verb and its masculine subject, otherwise there is an imperative preceded by a vocative.
