The Etymology of Quagmire
Walk across a bog and the ground trembles underfoot — that is precisely what quagmire describes. The word fuses quag, a now-extinct variant of 'quake' meaning marshy ground that shakes, with mire, from Old Norse mýrr ('bog, swamp'). It appeared in the 1570s to name a specific kind of dangerous terrain: not just wet ground, but ground that moves. The metaphorical leap to 'an inescapable difficult situation' followed by the early 18th century and has largely overtaken the literal sense. Political and military writers seized on the word — the Vietnam War was repeatedly called a quagmire, cementing its figurative use. The Old Norse element mýrr connects to Swedish myr and Icelandic mýri, all describing the boggy Scandinavian landscapes the Vikings knew well.
