依稀的线索

“[l]inguistic change can be said to have taken place when a new linguistic form, used by some sub-group within a speech community, is adopted by other members of that community and accepted as the norm.”

“While each speaker merely tries to reach her or his own communicative goals, she or he uses language in a particular way. If enough speakers behave in that way, language is changed.”
