One who wears clogs; a person who clogs or obstructs something.
From 'clog' (a wooden shoe or to obstruct) plus the agent suffix '-er' meaning 'one who does X.' The word follows standard English word-formation patterns established by the Middle English period.
In Lancashire and Yorkshire, 'cloggers' were respected tradespeople who made and sold wooden clogs—entire villages were known for their clogging industry, and it was a skilled craft passed down through families until modern shoes took over.
