Etymology: The word is a modern scientific coinage, not an ancient one. Its first part, "bio-", comes from Ancient Greek "bíos", meaning "life", and has been used as a combining form in English for scientific compounds. The second part, "modulator", is English "modulator", which comes from "modulate" and ultimately from Latin "modulus", a small measure or standard, which is itself a diminutive of "modus", meaning "measure" or "manner". The Latin sense of measuring and regulating is still visible in the modern meaning of adjusting something by degrees. "Modulator" itself entered English in the sense of something that regulates or adjusts a signal or process, and "biomodulator" joins the two: a substance or factor that adjusts the activity of living systems. Its meaning is therefore literal in construction, with no older sense to shift from. The Greek and Latin parts were only assembled into this compound in modern scientific English, so the classical roots did not carry this specific meaning in antiquity.

Synonyms: bioregulator, biological agent, modifying agent, biochemical agent, bioactive compound
