imperative indicated by e + verb (or in the negative by mai + verb). Some examples of the treatment of modality are as follows: Pono conveys obligation/necessity as in He pono i nā kamali'i a pau e maka'ala, "It's right for children all to beware", "All children should/must beware"; ability is conveyed by hiki as in Ua hiki i keia kamali'i ke heluhelu "Has enabled to this child to read", "This child can read". French French, like some other Romance languages, does not have a grammatically distinct class of modal auxiliary verbs; instead, it expresses modality using conjugated verbs followed by infinitives: for example, pouvoir "to be able" (Je peux aller, "I can go"), devoir "to have an obligation" (Je dois aller, "I must go"), and vouloir "to want" (Je veux aller "I want to go"). Italian Modal verbs in Italian form a distinct class (verbi modali or verbi servili). They can be easily recognized by the fact that they are the only group of verbs that does not have a fixed auxiliary verb for forming the perfect, but they can inherit it from the verb they accompany – Italian can have two different auxiliary verbs for forming the perfect, avere ("to have"), and essere ("to be"). There are in total four modal verbs in Italian: potere ("can"), volere ("want"), dovere ("must"), sapere ("to be able to"). Modal verbs in Italian are the only group of verbs allowed to follow this particular behavior. When they do not accompany other verbs, they all use avere ("to have") as a helping verb for forming the perfect. For example, the helping verb for the perfect of potere ("can") is avere ("have"), as in ho potuto (lit. "I-have been-able","I could"); nevertheless, when used together with a verb that has as auxiliary essere ("be"), potere inherits the auxiliary of the second verb. For example: ho visitato il castello (lit. "I-have visited the castle") / ho potuto visitare il castello (lit. "I-have been-able to-visit the castle","I could visit the castle"); but sono scappato (lit. "I-am escaped", "I have escaped") / sono potuto scappare (lit. "I-am been-able to-escape", "I could escape"). Note that, like in other Romance languages, there is no distinction between an infinitive and a bare infinitive in Italian, hence modal verbs are not the only group of verbs that accompanies an infinitive (where in English instead there would be the form with "to" –
