らPlural or associated group suffix
ら attaches to certain pronouns, names, and expressions for people to present them as a group. After a name, it can mean that person together with relevant associates.
What kind of group it marks
彼ら normally presents several male or mixed-gender people already understood from context. 僕ら presents a group including the speaker and is common in casual speech. The suffix marks a group but does not state its exact size.
Common pronoun forms
These are established combinations rather than a rule that freely creates the plural of every noun.
A person and associates
After a person's name, ら can mean that person and the other people associated with them in the situation. The context should make the associates identifiable.
発表を担当するのは田中さんと二人の同僚だ。田中さんらは午前中に会場へ着いた。
Tanaka and two colleagues are giving the presentation. Tanaka and the others arrived at the venue in the morning.
AnalyzeThe first sentence identifies the associates, so the group in the second sentence is clear.
Compact labels in writing
救助隊員らは夜まで捜索を続けた。
The rescue workers continued the search until night.
AnalyzeHuman role labels followed by the suffix are concise and common in reports and other informational writing.
Choosing between two group suffixes
ら and たち overlap, but they are not freely interchangeable. The safest approach is to learn common combinations: 彼ら is a standard neutral form, while the choice with first-person words varies with familiarity, social distance, region, and speaker. Do not reduce the difference to a universal rule that one suffix is polite and the other rude.
