Surface Forms

blastocoel singular
blastocoels plural

Morphology

blastocoel = blastula (opaque) = blasto + coel

The term is built from specialist Greek combining forms ('blasto-' and 'coel-') that are unfamiliar to average learners and whose surface forms do not match common English words.

Etymology

Blastocoel comes from Greek parts blasto- meaning 'bud' or 'early cell' and -coel meaning 'hollow' or 'cavity'. So a blastocoel is the 'hollow' or fluid-filled space inside an early embryo.
