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. As will be clear from the examples below, Venetian subject clitics are neither "redundant" nor "pleonastic" because they provide specific information, not present on verbal endings. Independent/emphatic pronouns (e.g. ti), on the contrary, are optional.
| (Ti) te jèra onto | (Tu) eri sporco | You were dirty (ven. lit. "(You) you were dirty") | |
| El can el jèra/jèri/xeri onto | Il cane era sporco | The dog was dirty (ven. lit. "The dog he was dirty") | |
| (Ti) te te à/gà/ghè domandà | (Tu) ti sei domandato | You have asked yourself (ven. lit. "(You) yourself have asked") |
The clitic subject pronoun (te, el/ła, i/łe) 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:
| Marco 'l canta ben, dai! | Marco canta ben, dai! | Marco canta ben, dai! | Marco canta bene, dai! | |
| Mark sings well, you have to admit it! (exclamative) | Mark sing well, come on! (Imperative) | Excalmative and Imperative | Exclamative and Imperative |
Indeed, the verbal forms requiring subject clitics can often change or even drop their endings without problems of confusion because the clitic itself provide the necessary information (in Piedmontese and Milanese the clitic is not sufficient to mark the verb and often requires the cooccurence of a specific ending). Because Venetian subject clitics mark number (e.g. te = 2nd singular, el = 3rd singular, i = 3rd plural) and gender (ła = feminine 3rd singular, łe = feminine 3rd plural), they convey specific information that is not (or might not be) present on the endings. Thus, they act like a bridge that provide number and gender agreement between verb and subject (some languages, like Hebrew or Basque may show number/gender agreement on verbal endings). Thus, although some traditional grammars consider subject clitics as "redundant" or "pleonastic" elements, Venetian subject clitics are neither redundant nor pleonastic.
The clitics are the same in whole Veneto with two exceptions: te becomes ti in Venice (but is different from emphatic TI!) and becomes tu in some bellunese areas. El becomes Al in bellunese.
Such variations in last and internal vowels do not block reciprocal comprehension between people in Veneto because what is felt as important to mark the verb is the clitic ("te, el").
Also general Venetian forms exist with no endings:
Note that when the subject is postverbal (motion verbs, unaccusative verbs) the clitic is banned and the past participle of compound forms (if any) is invariably masc.singular, yielding a semi-impersonal form which does not exist in Italian:
In Italian the past participle is always inflected while in the Venetian in the impersonal form it is invariable and the verb has no plural (fem.) clitic, differently from the normal flection.
