Another Word for “Slow”

- Low speed: sluggish, plodding, crawling, creeping, dawdling
- Gradual process: gradual, incremental, progressive, measured
- Lack of promptness: delayed, tardy, late, behind schedule
- Mental dullness: dull, dim, obtuse, dense, slow-witted

When Not to Use “Slow”
“Slow” can become too vague when you need to be specific about what kind of slowness you are describing.

A more precise sentence could be:
“The system has a response time of over five seconds.”
Similarly, avoid using “slow” to describe mental ability in professional or formal contexts. Use “deliberate”, “methodical”, or “thorough” instead.
