LAG /læɡ/
nounverbB2
generalcolloquial

A noticeable delay or slow response in a computer, game, or network; (verb) to fall behind or move slowly.

In gaming, 'lag' is the colloquial and experiential term for the stuttering, freezing, or delayed response caused by high latency or poor system performance.

The story behind the word. The word originally described a person who moved slowly or fell behind a group (a 'laggard'). With the rise of computing and online networks, it was naturally adapted to describe data packets or software frames falling behind their expected schedule.

Word relationships

  • stutter: 'Stutter' refers specifically to visual frame-rate drops, whereas 'lag' usually refers to network-induced delays.

Commonly confused with

When not to use

Avoid using 'lag' in formal academic papers when 'latency' or 'propagation delay' would be more precise, though 'lag' is perfectly acceptable in general tech discussions.

Fun facts

  • The term 'lag' has become so ubiquitous that gamers use it in real life to describe feeling tired or slow to respond (e.g., 'My brain is lagging today').
