drop lock
C1Technical
Definition
Meaning
A locking mechanism that secures by dropping into place, typically a bolt or latch.
1) In computing, a type of synchronization primitive that protects a shared resource. 2) In sports (especially basketball), a defensive strategy where a player temporarily 'drops' coverage to 'lock' onto another player. 3) In finance, a provision that fixes an interest rate for a loan after it drops to a predetermined level.
Linguistics
Semantic Notes
The term is often domain-specific. The core mechanical meaning is literal, while computing and sports uses are metaphorical extensions based on the actions 'drop' (descend/cease) and 'lock' (secure/engage). The financial term is jargon.

Common Mistakes
- Using 'drop lock' as a verb (e.g., 'I will drop lock the door'). It is primarily a noun compound.
