Yes! Thank you. No wonder I wasn't able to find it as I strongly held my belief that it was 4 letters. Love this place.
It's odd how a word can feel "on the tip of your tongue" and intuitions about its number of sounds and their characteristics can be remarkably accurate, especially if you consider the interposition of linguistically similar sounds. And it can be totally misleading when your memories are incorrect, to the point for me at least of making it nearly impossible to recall a word until I have shifted focus to something else.
