In comparatives^x, Adjectives^x

Of course, it's not the number, but I want to know if there are more than those ones. Thanks for your reply.

Hi Philip, Thanks for your reply. What I see is that there are very few adjectives that are involved with that rule, I've found 11: bad, big, fat, red, sad, tan, thin, wet, hot, flat, drab. Thanks!

I need some help to find adjectives that double the last consonant when working as comparatives. I have some: wet, big, fat, thin, sad, red, hot, .. Wold you help with some others? Thanks in advance.
