Questions & Answers about El pájaro y el árbol se traen un beneficio el uno al otro.
Why do we need el uno al otro if se already means 'each other' here?
The pronoun se can be reciprocal ('each other') or reflexive ('themselves'). Without the extra clarification, se traen un beneficio could technically mean 'they bring a benefit to themselves.' Adding el uno al otro completely removes this ambiguity and strongly emphasizes that the bird and tree help each other.
Why is it el uno al otro in the singular instead of plural los unos a los otros?
Why are we using the masculine form el uno and el otro?
The phrase has to match the grammatical gender of the subjects. Both el pájaro (the bird) and el árbol (the tree) are masculine words, so we use the masculine uno and otro. If we were talking about two feminine nouns, like a bee (la abeja) and a flower (la flor), it would change to la una a la otra.
Where does the al in el uno al otro come from?
The word al is a mandatory contraction of the preposition a (to) and the masculine article el (the). Because they bring a benefit to each other, the preposition a connects the two halves of the phrase: el uno a el otro. Spanish requires you to combine a and el together into al.
Could I use mutuamente in this sentence instead?
