Resembling an embryo in structure or appearance; having embryo-like characteristics.
From Greek embryon (embryo) plus -oid (from eidos, meaning form or shape). The suffix creates a comparison meaning 'like' or 'resembling.'
The suffix -oid is incredibly useful in science—it creates a whole category of 'like' words (humanoid, spheroid, android) allowing scientists to describe things that resemble something without being exactly that thing.
