Before grabbing a slow synonym, decide if the slowness pleases you or annoys you. Leisurely and unhurried praise a relaxed pace, gradual describes steady change, while sluggish and delayed complain. Pick wrongly and a calm Sunday walk sounds like a broken laptop.
This page offers words sorted by attitude, a strength strip from gentle to extreme, and test sentences. There is also a short list for slow as a verb, since slow down has its own family of replacements.

Calling a person slow can mean they learn slowly, which is unkind. Describe the task instead.
Positive, neutral or negative? Sorting the words
A slow pace may be a treat or a flaw, and the replacement should carry the same attitude.
| Tone | Words | Typical use |
|---|---|---|
| Positive | leisurely, unhurried, relaxed, measured, deliberate | A leisurely lunch by the river |
| Neutral | gradual, steady, lengthy, late | A gradual rise in prices |
| Negative | sluggish, plodding, dragging, protracted, tardy | Sluggish sales this quarter |
Measured and deliberate suggest care, so they suit a speaker or a decision. Sluggish suits engines, economies and people who slept badly.
Slow synonym strength, unhurried up to glacial
The colored chips above rise in intensity. Unhurried is a choice, not a flaw. Gradual means change in small steps. Sluggish means slower than it should be. Plodding adds heaviness and boredom, and glacial is the most dramatic, a pace so slow it hardly moves at all.
Glacial is figurative, so save it for real frustration: the glacial pace of the planning office.

Kind ways to talk about people
Some older words for a person who learns slowly are insulting, so they are left off this list. If you need to describe pace of learning, talk about the situation: needs more time, works at a careful pace, prefers step-by-step instructions. Tardy and unpunctual describe lateness only and are safe in a school report.
Lazy is not a synonym. A slow worker may be thorough, and the lazy synonyms page is about unwillingness, a separate idea.
Idioms that mean slow
Casual English has colorful options: at a snail's pace, slow as molasses (American), dragging its feet (for a reluctant group), taking its sweet time and taking forever. Keep them out of formal essays, where gradual or protracted sounds better.
Antonyms: words for speed
The opposite of slow is usually fast or quick. Rapid and swift are a little more formal, brisk suits walking and trade, and prompt suits replies. For a busy shop, say busy or bustling. More options sit on the fast synonyms and quick synonyms pages, while our describing words collection covers other adjectives.
