Comparison of Italian and Spanish

Auxiliary Verbs

• Spanish has the complication of two verbs meaning 'to be', namely, ser and estar. The first is used mainly for permanent states, whereas the second is used mainly for temporary states. The equivalent verbs essere and stare exist in Italian, but stare is used much less frequently than estar. Compare the Italian Dov'è? and Sono stanco with the Spanish ¿Dónde está? and Estoy cansado.
• Italian use of stare follows Spanish, however, in the construction of the gerund (see below) and also in a few set phrases (compare Sto bene with Estoy bien).
• The main verb in Italian meaning 'to have' is avere. In Spanish it is tener. However, whereas Italian uses avere to form compound tenses, Spanish does not use tener. Instead, Spanish has the special auxiliary verb haber.
• To say 'there is', 'there are' in Italian, use ci plus essere. For example, c'è una macchina, ci sono delle donne, c'era molta gente. In Spanish, you just use haber. For example, hay un coche, hay unas mujeres, había mucha gente.
• Italian has three main modal auxiliary verbs: dovere, potere and volere. One can use some other verbs, such as sapere, as modals. There are also several impersonal verbs, such as bastare, bisognare, convenire that behave as modals.
• Spanish also has the three modal verbs deber, poder and querer. However, in Spanish it is common to use tener que in place of deber. (This is similar to the English 'to have to'.) Impersonal verbs include haber que and hacer falta.
• It should be noted that the Spanish modal querer followed by a person or animal means 'to love'. (To express a similar sentiment in Italian, one can use volere bene (a qualcuno).)
