To remove a clog or blockage from something; to unclog (informal or technical term).
From de- (to remove) + clog (a blockage, from Middle Dutch klokken meaning to block up). This modern verb blends Latin prefix with English noun.
You won't find 'dechlog' in most dictionaries, but plumbers and drain specialists use it constantly—'I'll dechlog that drain for you'—showing how technical trades create practical language that formal dictionaries never quite catch.
