Object pronouns -direct and indirect object pronouns- substitute the noun. In English these are ‘me’, ‘him’, ‘her’ and so on. For example, in the sentence ‘Give Sam the pen,’ Sam is a noun, which can be changed to ‘Give her the pen.’ In Spanish the pronoun either comes before the verb as a separate word or after joined with the verb, when are used with affirmative imperative, an infinitive or a gerund. For example:
Le da el boli (he is giving her the pen).
Voy a darle el boli (I am going to give her the pen).
‘Dale el boli’ (give her the pen).
Estoy dándole el bolí (I am giving her the pen).
Gracias por tu aportación. Feliz semana.
Muy buen ejercicio. Muxchas gracias. Lo único es que en la frase tres falta el auxiliar del pretérito perfecto para que la frase quede completa. (Me lo ha regalado …)
Muchísimas gracias, Laura. Ya está corregido.
