N.B. These verbs are different even in their past form!

The verb “volerci“, for composed tenses, requires the auxiliary “essere“(to be):

Example:

Ci sono volute* 0 ore per preparare questa torta! (It took two hours to make this cake)

*since we’re using “essere”, we must agree the past participle to the subject, that in this case is “0 ore”, so feminine and plural

The verb “metterci“, instead, requires the auxiliary “avere“ (to have):

Example:

Ci ho messo 0 ore per preparare questa torta! (It took me two hours to make this cake)
