Key Comparisons

ABOVE vs OVER (Most Confusing!)

ContextABOVEOVERDifference
Positionhigher thancovering/aboveabove = no contact, over = covering
Movement❌ not used✅ movement acrossover = movement, above = static
Quantity❌ not used✅ more thanover = more than

Examples:

Position:

  • ✅ “The lamp is above the desk.” (灯在桌子上方 - 不接触)
  • ✅ “Put a cloth over the table.” (在桌子上盖块布 - 覆盖)

Movement:

  • ❌ “The bird flew above the tree.” → ✅ “The bird flew over the tree.” (鸟飞过树)

Quantity:

  • ✅ “There were over 50 people.” (超过 50 人)
  • ❌ “There were above 50 people.” (不自然)

Memory trick:

  • above = “a"bove = “a"bove the surface (no contact)
  • over = “o"ver = “o"ver and covering
