drop
The Italian word 'cadere' is used to express the action of dropping or falling. It can be used both transitively and intransitively. For example, 'La mela cade dall'albero' means 'The apple drops from the tree'. In a transitive sense, 'Cadere un oggetto' means 'To drop an object'.
The apple has fallen from the tree
In this sentence, 'caduta' is the past participle of the verb 'cadere', which means 'to fall'. It is used in conjunction with 'è', the third person singular form of the auxiliary verb 'essere', to form the passato prossimo, a common past tense in Italian which describes an event that happened at a specific time in the past. The noun 'mela' means 'apple', 'dall'albero' is a prepositional phrase meaning 'from the tree'.
I don't want to fall into your trap
This is an example of using 'cadere' in the infinite form in a sentence. The subject ‘Non voglio’ translates as 'I do not want', ‘nel tuo tranello’ translates to 'into your trap'. Thus the overall translation equates to 'I do not want to fall into your trap'.
I always fall into the same mistake
The verb 'Cado' is the first person singular, present tense form of 'cadere' and translates to 'I fall'. 'Sempre' translates to 'always', 'nel solito errore' translates to 'into the usual mistake'. Therefore this sentence means 'I always fall into the same mistake' which is a way of saying that I always make the same mistake.
