Morphology
gemmule = gemma (opaque) = gemm + ule
The word is formed with a Latin diminutive and denotes a technical biological structure; learners unfamiliar with the botanical term 'gemma' will not reliably derive the meaning.
Etymology
Gemmule comes from the Latin gemma meaning 'bud' and the small ending -ule, so it literally means 'little bud'. In sponges and some plants, a gemmule is a small reproductive part that can grow into a new individual, so the origin explains the word's modern use for these tiny buds.
