Morphology
sediment = sed + ment
The noun appears to be built from the combining form 'sed-' plus the noun-forming suffix '-ment'; 'sed' is not a standalone modern English word, so learners cannot reliably derive the meaning from familiar morphemes.
Etymology
Sediment comes from the Latin root sedere meaning 'to sit'. So sediment is the solid stuff that 'sits' at the bottom of a liquid.
