How bio works

The root 'bio' typically functions as a prefix, turning nouns and adjectives into words about life or living processes. It remains stable in spelling across its combinations, though in 'symbiosis' it appears mid-word after the prefix 'sym-' (a variant of 'syn-' assimilated before 'b').

Watch out: The word 'biome' can tempt learners to see '-ome' as unrelated, but 'bio' here is genuine; more truly, 'biography' should not be confused with 'bibliograph-' words, where 'biblio-' means book, not life.
