Slip

Return to > Dictionary

1. Definition + Rich Everyday Explanation

Slip (verb / noun) = to lose balance or control because a surface is smooth or wet; to make a small mistake; to move or pass quietly or unnoticed.

The core idea of slip is loss of control without impact. Unlike trip, nothing blocks your foot. Unlike stumble, the problem is not clumsiness. With slip, the surface itself betrays you — it’s smooth, wet, icy, or metaphorically unsafe.

In everyday English, slip is extremely common both literally (slipping on ice) and metaphorically (a slip of the tongue, letting information slip, small mistakes at work).

MEANING 1: Lose Balance on a Smooth or Wet Surface — VERY COMMON

Literally, to slip means your foot slides because there is not enough grip. You may fall, or you may recover quickly. The cause is the surface, not an object.

MEANING 2: Make a Small Mistake — VERY COMMON

Metaphorically, a slip is a minor, often unintentional mistake. It’s not serious failure — just a moment where control drops. This use is common in speech, writing, and behaviour.

MEANING 3: Move or Pass Quietly or Unnoticed

To slip somewhere means to enter or leave quietly, without drawing attention. Information, time, or opportunities can also slip away.

Examples from the street:

• “I slipped on the ice” → the surface was slippery
• “That was just a slip” → a small mistake
• “He slipped out quietly” → he left unnoticed

2. Most Common Patterns

Slip as physical movement — VERY COMMON:

• slip on + surface → ice, water, wet floor
• slip and fall → lose balance completely

Slip as mistake — VERY COMMON:

• a slip of the tongue → say something unintentionally
• make a slip → commit a small error
• slip up → make a mistake

Slip as quiet movement:

• slip in/out → enter or leave quietly
• let something slip → fail to keep control of information or time
