Another word for slow depends on the context. Common alternatives include unhurried, leisurely, gradual, sluggish, delayed, steady, leisurely, and sluggish. For formal writing, gradual or delayed may work better; for relaxed movement, unhurried or leisurely is often more precise.
What Does Slow Mean?
Definition
Slow generally describes something that moves, happens, develops, or operates without much speed. It can describe a person, physical movement, process, activity, business, technology, or rate of progress.
For example:
- The car is slow.
- She is a slow reader.
- The recovery was slow.
- Business was slow this month.
Cambridge also identifies several distinct uses of slow, including low physical speed, gradual progress, reduced business activity, and a person’s slower ability to understand or learn.
Common Uses
The best synonym changes according to what “slow” means in the sentence.
Slow movement:
Use unhurried, leisurely, sluggish, crawling, or creeping.
Slow progress or change:
Use gradual, steady, prolonged, or delayed.
Slow business activity:
Use quiet, inactive, sluggish, or slack.
Slow response:
Use delayed, hesitant, or reluctant, depending on the intended meaning.
Slow technology or performance:
Use sluggish, lagging, poky, or unresponsive.
This distinction matters because a synonym should preserve the original meaning rather than merely sound similar.

Synonyms by Context
Formal Writing
For formal and academic writing, choose words that describe why something is slow.
Gradual is useful for a change that develops over time:

Prolonged emphasizes that something continues for a long period:

Delayed is appropriate when something occurs later than expected:

Academic writing benefits from precise alternatives.
