Morphology

decohere = cohere (transparent) = de + cohere

For learners who know 'cohere', the meaning 'lose coherence' follows directly from the productive reversative prefix 'de-'.

Etymology

Decohere breaks into de- ('remove' or 'not') and cohere ('to stick together'), the same root you see in cohesive. So, to decohere is for parts to stop 'sticking together' and lose unity or order.
