～ら

～ら is a casual, spoken-form suffix that attaches to certain pronouns (e.g., 私ら, 僕ら, あなたら) and demonstratives (e.g., これら, それら, あれら) to indicate a plural meaning like we, they, you all, or these/those. It is common in informal conversation and may carry a masculine or rough nuance depending on the speaker. It is not used in formal writing; for formal plural, use 私たち, あなたたち, これら, それら, あれら (the latter being less common). Common patterns include pronoun + ら for personal groups and demonstrative + ら for plural forms of those demonstratives.
