talle
The Estonian word "talle" means "to him/her" or "to the lamb," depending on the context.
In this sentence, "talle" is used as the allative case form of the pronoun meaning 'him' or 'her', indicating the direction or recipient of the action (to whom the book was given).
Andsin talle raamatu.
I gave the book to him/her.
Here, "talle" represents the third person singular pronoun in the allative case, which is required by the verb "meeldima" (to like) to indicate who likes the activity.
Meeldib talle kõndida metsas.
He/she likes walking in the forest.
In this sentence, "talle" again takes the allative case form of the pronoun, reflecting for whom the necessity applies.
