Question 1

Why use l'un et l'autre here instead of just les deux?

Accepted Answer

While entre les deux (between the two) is perfectly correct, using l'un et l'autre (one and the other) emphasizes the separation or opposition between the two parties. It highlights them as distinct entities rather than a single combined unit, which fits perfectly with the word conflit (conflict).

Question 2

How do prepositions like entre work with l'un et l'autre? Do I need to repeat the preposition?

Accepted Answer

You only use the preposition once here, right before the phrase: entre l'un et l'autre. Because the phrase acts as a single concept linking the two parties, the preposition applies to the whole thing. Note that this is different from reciprocal phrases (meaning 'each other'), where the preposition splits the phrase, as in ils parlent l'un à l'autre (they speak to each other).

Question 3

Would l'un et l'autre change if the two things in conflict were feminine or plural?

Accepted Answer

Yes! These pronouns must agree in gender and number with the nouns they replace. If the conflict were between two feminine entities, such as two companies (les entreprises), it would become entre l'une et l'autre. If it were between two plural masculine groups, you would use entre les uns et les autres.

Question 4

Is the l' in l'un mandatory, or could I just say entre un et l'autre?

Accepted Answer

The l' is mandatory. Whenever you use these contrast and distribution pronouns in French, they require the definite article. You must always say l'un(e), never just un(e).
