l'un l'autre

Pronoun

 * 1)  each other, one another

Usage notes

 * As the reflexive pronoun can indicate reciprocity, the use of  in conjunction with pronominal verbs is not always necessary and may sound unnatural or even incorrect. However,  can be included to clarify that an action occurs mutually between two (or more) subjects rather than each individual subject toward themselves, especially with transitive verbs that are not used in the pronominal form. Consider the following examples:
 * Prepositions or prepositional phrases required by the verb are inserted between the pronominal units. For example:, , , , etc.
