Morphology

osmosis = osmo + osis

Formed from Greek combining form 'osmo-' + '-osis'; these are not productive standalone English words for average learners, so the meaning cannot be reliably derived from the parts.

Etymology

The word osmosis comes from the Greek root osm- meaning 'push' or 'thrust' and the ending -osis meaning 'a process'. So osmosis is like a slow 'push' of water through a thin wall that moves water from the side with more to the side with less, helping the amounts become even on both sides.
