Hi Sean, In italian as in English we have direct pronouns, which come before or soon after a transitive verb that doesn't have the prepositon A, for example "mangiare": 1. L'ho (la ho) mangiata= ho mangiato la pizza. 2. Mangiala (mangia la pizza). The direct pronoun comes after the verb when you have an imperative, an infinite verb (mangiare), gerundio (mangiando) o two verbs ( vieni a mangiarla). 3. The direct pronouns are: mi (me), ti (you), ci (us), vi (you), lo (him but also masculine object), la (her but also feminine object) , li and le are the plural of lo and la. 4. Indirect pronouns usually go before a verb with the prepisition A (piacere a, parlare a, dire a): mi - a me, ti - a te, ci - a noi, vi - a voi, gli - a lui/a loro, le - a lei. For example: ti va di andare al cinema? (Do you fancy going to the cinema?) They go after the verb when it is an imperative, gerundio or infinitive. For example : "scrivimi". 5. In Italian sometimes we join the indirect and direct pronouns and we have "pronomi combinati": me lo, me la, me li, ecc.. They can come before and after the verb when we have imperative, infinite and gerund.

Poi gli ho detto... It Can be both him and them, the pronouns always depend on the context of the sentence. For example : Lui voleva venire a casa mia e poi gli ho detto che non poteva venire. Loro volevano vendermi dei biscotti ma io gli ho detto che non potevo comprarli.
