  • "We're interested in the kind of aerenchyma plants develop soon after sprouting.

    Academic text (1997)

Morphology

aerenchyma = aer + enchyma

The word is built from specialized Greek combining forms ('aer-' + 'enchyma') that are not standalone or familiar English base words, so an average B1 learner cannot reliably derive the meaning from its parts.

Etymology

Aerenchyma comes from the parts aer- 'air' and -enchyma 'poured in'. So it is like 'air poured into' the plant tissue, which helps plants carry oxygen to their roots and sometimes float in water.
