Morphology

bilabial = labial (semi-transparent) = bi + labial

Formally 'bi-' (two/both) + 'labial' (relating to the lips) yields 'using both lips', but 'labial' is a technical term that may be unfamiliar to average learners.

Etymology

Bilabial comes from the Latin parts bi- 'two' and labium 'lip'. It describes a speech sound made by using both lips together, so sounds like /p/ and /m/ are called bilabial.
