与【yǔ】

与 joins two nouns ("and") or names who an action is done with ("with"). It does the work of 和 and 跟 in writing, titles and formal speech.

In titles

Titles of books, films, articles and courses use 与 almost by default, because 和 reads as conversational.

With a partner

与 + person or group goes before the verb: 与…合作 "work with", 与…交流 "communicate with", 与…见面 "meet with". 与…有关 "be related to" and 与…无关 "have nothing to do with" are the commonest pair of all.

Comparisons with 与 (与…相比, 与…一样) have their own entry.

Nouns only

As "and", 与 joins nouns and noun phrases. It can't join two verbs, two adjectives or two clauses.

• × 我去了商店与买了水果 → 我去了商店，买了水果
• × 他高与帅 → 他又高又帅

In a list of three or more, 与 goes before the last item only, with 、 between the others.
