PC

The term "PC" is a modern initialism, first emerging in the late 1970s. It originated as an abbreviation for "personal computer," a term coined to distinguish affordable, single-user machines like the IBM PC from large, institutional mainframes. The initialism was later adopted in the late 20th century to abbreviate the phrase "politically correct," reflecting a societal focus on language and policies intended to avoid offense or disadvantage. Thus, "PC" represents a linguistic shortcut where two distinct, complex concepts are efficiently encoded into a two-letter symbol, its meaning entirely dependent on context.

This is an initialism, not a word formed from combinable morphemes. The letters 'P' and 'C' stand for the separate words "personal" and "computer" (or "politically correct").
