I'm looking for a website that lists sound words like ツルツル and gives definitions. Its okay if it is a Japanese website but prefer English.

Thanks

ALC's website has around 300 with example sentences (click "擬音語・擬態語集" on the ALC page). I made a spreadsheet for convenience.

That's amazing. Thanks

For reference, it's called "Onomatopoeia"

Nihongo Resources' dictionary works as well.

Katsuo, you have a spreadsheet for everything .
