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').
