mutagen

The word 'mutagen' is a modern scientific compound, formed in the early 20th century from two classical roots. The first element, 'muta-', is derived from the Latin verb mutare, meaning 'to change', which itself traces back to the Proto-Indo-European root mei-, conveying the sense of 'to change, go, move'. The second element, '-gen', comes from the Greek combining form -genēs, meaning 'born of' or 'producer', related to the verb gignesthai (to be born, become). Thus, the term's literal construction as 'a producer of change' directly and logically describes its function: an agent that produces alterations in genetic material.

Structure: muta (change) + gen (producer) 'muta' originates from Latin mutare (to change). 'gen' originates from Greek -genēs (born of, produced from).
