Crawling refers to moving slowly on hands and knees or by dragging oneself along the ground. It's usually seen in young children learning to walk.
When people talk about something being crawly, they often mean that it moves in a slow and awkward way, like a baby taking its first steps. For example, if you see a caterpillar making its way across the floor, someone might say "Look at how crawly it is!" They're describing how slowly and deliberately the caterpillar moves. Sometimes people also use "crawling" to describe something that's spreading or moving in a slow, gradual way, like a stain on fabric creeping across the surface.
