Paronymic etymology relying on the identical initial sequence [bl-s]. The germ is defined by its growth, and βλώσκω is understood here simply as an equivalent of any motion verb in so far as growth is a kind of motion. The etymology implies one formal manipulation, the change of [ō] into [a]. The initial notation that [b] and [m] are close to each other is interesting: it relies on cases of assimilation such as σεμνός / σέβομαι and on cases of epenthetic [b], the canonic example of which is precisely βλώσκω (aorist ἔμολον, future μολοῦμαι).
