Origin

bunker · noun, verb

  1. GermanBunker
  2. Proto-Indo-European*bʰenǵʰ-“thick”
  3. Proto-Germanic*bunkô“a heap, pile; a bump, lump, a crowd”
  4. Old Norsebunki“a heap”
  5. Early Scotsbunker
  6. Scotsbunker“bench; pew; window-seat; sand pit (especially in golf); coal receptacle; sleeping berth, bunk”
  7. Englishbunker

The origin of the noun is uncertain; the earliest sense is sense 7.1 (“box or chest, the lid of which serves as a seat”), from Scots bunker (“bench; pew; window-seat; sand pit (especially in golf); coal receptacle; sleeping berth, bunk”), from Early Scots bunker, bunkur, bonker (“a chest or box, often serving as a seat”), probably from Old Norse bunki (“a heap”) (probably whence bunk (“sleeping berth in a ship, train, etc.”)), from Proto-Germanic *bunkô (“a heap, pile; a bump, lump, a crowd”), perhaps from Proto-Indo-European *bʰenǵʰ- (“thick”) or *bʰeg- (“to billow, swell; to arch, bend, curve (?)”). Compare Middle Low German bunge (“drum, container”), Middle High German bunge (“drum”). Sense 1 (“hardened shelter designed to protect the inhabitants from falling bombs or other attacks”) was derived from German Bunker during World War II, which was itself from bunker (“large bin or container for storing coal”) (sense 5). The verb is derived from the noun.
