Le and tenses, past, present and future

Question

I have an idea but, im very curious what it means when there is a seemingly unnecessary " Le " in front of the verb. The material i am covering right Now is in tenses to be sure. i. e. Ella le escribe una carta a su abuelo. Ella le escribió una carta a su abuela. Ella le di un libro a su hermano Ella le da un libro a su hermano

Answer 1

ella (her) le (to him,grandfather) escribe (she writes) una a carta a su abuelo (a letter to her grandfather)

thats how it should sound to the Spanish ear, think of it this way.....you know what its like when we understand a foreigner yet what they say doesnt sound right to the English speakers ear

Hope this helps

Answer 2

They say it is a rule that you must always use an indirect object pronoun whenever an indirect object exists.

Answer 3

It sounds better with "LE", despite the redundancy. "Ella le escribe una carta a su abuelo" If we know we are talking about his grantphather => "Ella le escribe una carta". "Ella me escribe una carta" = "Ella me escribe una carta a mí".

"Ella le escribió una carta a su abuela" = "Ella LA escribió una carta".

"Ella le DIO un libro a su hermano". It sounds much better if you say "LE". Ella dio un libro a su hermano => Better: "Ella le dio / le entregó / le dijo ... a su hermano".
