When something or someone moves at a snail's pace, it means that it's moving extremely slowly. If you want to express this idea with different words, you could use synonyms like sluggishly, crawlingly, or lethargically. These words convey the sense of a slow and gradual movement, just like a snail. Other synonyms for "moved at snail pace" include ploddingly, tardily, and slowly but surely. You could also use metaphors like "moving like molasses" or "creeping like a glacier" to describe this kind of slow motion. Whatever words you choose, they can help you capture the sense of a slow-moving object or person.
