I don't know how you can say it is "technically incorrect". The first definition in Random House (crawl - WordReference.com Dictionary of English) is:I'd say that 'crawl' for snakes is technically incorrect but common.
It sounded off to me as well, and that's how I ended up here on Saturday, but after reading a few online sources, I see that it's not incorrect. I'd found the phrase "...snakes crawled off a rock..." while translating instructional materials and wondered if I should query that, but I guess not. It was a choice to use 'crawl.'I’m with those who say that as correct as it may technically be, it sounds totally off. The idea of a snake crawling just doesn’t compute for me.
Snakes definitely don't creep around here!*Crawl is fine for snakes where I live. It is also fine for what your skin does when you see a snake.
Creep is another choice.
