Source and review context

This entry combines structured lexical data with WordToolSet review checks. Definitions, examples, synonyms, and usage notes may come from different source tables, so the page is designed to show evidence from more than one angle before you rely on "bunker" in a final draft.

If a word has several senses, prefer the sense that matches your sentence's grammar and surrounding context. A correct definition can still be the wrong choice when the sentence needs a different register, emphasis, or level of specificity.

Before you rely on this definition

Read the first definition as a starting point, then check the example, synonyms, and part of speech before treating "bunker" as the right word for your sentence.

If your draft is formal, technical, persuasive, or sensitive, compare "bunker" with a nearby alternative so the final choice matches both meaning and reader expectation.

Compare nearby meanings

  • Use synonyms when you need a softer, stronger, simpler, or more specific word.
  • Use antonyms to check the boundary of the meaning and avoid accidental contrast.
  • Use the example sentence to confirm the word behaves naturally in context.
  • Keep the original wording when a replacement adds complexity without improving precision.

Definition decision workflow

1. Identify the role

Check whether "bunker" is acting as name, noun, verb, slang in your sentence. A definition is only useful when the grammar matches the way the word is being used.

2. Test the nearest option

Compare it with "sand trap" and other nearby choices to see whether the sentence needs a softer, stronger, or more familiar word.

3. Confirm with context

Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.

Review note: Definition pages are checked for source coverage, sentence evidence, synonym support, and editorial insight before they are treated as approval-ready pages. If the evidence is too thin, the page remains available to users but is kept out of the approval-facing indexed inventory.

Final meaning check

Before publishing a sentence with "bunker", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.

When the definition, synonym evidence, and example context point in the same direction, the word is usually a safer choice. When they conflict, revise the sentence or choose a clearer alternative.

Etymology

Etymology 1

The origin of the noun is uncertain; the earliest sense is sense 6.1 (“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.

Etymology 2

From bunk (“to fail to attend school or work without permission, to play truant”) + -er (suffix forming agent nouns indicating a person or thing that does an action).

Etymology 3

Clipping of mossbunker, a variant of mossbanker, from Dutch marsbanker (“common scad or Atlantic horse mackerel (Trachurus trachurus)”), from Marsdiep (“deep tide-race between Den Helder and Texel in the Netherlands”) + bank (“shallow part of the sea near a coast”) + -er (suffix forming nouns denoting male inhabitants of a place).
