regrowth

The word 'regrowth' is a transparent Modern English compound formed by attaching the Latin-derived prefix 're-' to the native English noun 'growth'. The prefix 're-', from Latin, carries its core meaning of "again" or "anew," a function it has maintained since its Proto-Indo-European root wret-, meaning "to turn" or "to roll," which evolved into concepts of return and repetition. The base word 'growth' originates from the Old English 'grōwan' (to grow), which traces back to the Proto-Germanic grōan- and ultimately to the Proto-Indo-European ghreh₁-, meaning "to grow, become green." The logical construction of the word is perfectly literal: the act ('growth') happening once more ('re-'), directly describing the renewal of biological tissue, hair, or vegetation after loss or damage.
