Third person direct object clitic pronouns have several forms, depending on their position with relation to the verb and on the verb's ending. If the pronoun is enclitic and the verb ends with a consonant, or if the pronoun is mesoclitic and the root of the verb ends with a consonant, then that consonant is elided, and an "l" is added to the beginning of the pronoun. If the pronoun is enclitic and the verb ends with a nasal diphthong (spelled "-ão", "-am", "-em", "-ém", "-êm", "-õe", or "-õem"), an "n" is added to the beginning of the pronoun. The same happens after other clitic pronouns, and after the adverbial particle "eis".
