Pro Tip
Remember the preposition
Say 'a gap in the fence' for a missing part, but 'a gap between the fence and the wall' for a space separating two things.
Gold Rule
Gap vs. Gap in vs. Gap between
Use 'gap' alone for a physical opening, 'gap in' for missing content, and 'gap between' for a space separating two items.
Word Origin
From Old Norse 'gap' meaning 'chasm, opening', related to Old English 'geap' and German 'Gappe'.
Usage Notes
Use 'gap' with 'in' for abstract missing parts (e.g., 'gap in knowledge') and with 'between' for physical separations (e.g., 'gap between walls').
