Adjectives that double the last consonant

0 I don't have time to add to your list right now, but if you're looking for a general rule: if the vowel before is "short" and there is no intervening consonant the consonant is doubled. 0-

00Absolutely agree about 01u01i01b00bad02b00,02i02u00 it was a huge slip. But I'm not sure about 01b01i01u00tan02u02i02b00, in several lists they accepted as an adjective; moreover 00I found this:02p

01p

01i00adj.02i00, 01b

0You may be able to find tanner/tannest in a few dictionaries, but most dictionaries I checked do not list them as acceptable words (including the Oxford English Dictionary). I would also object their status of being valid English words or even valid concepts in any language. We know that red, green and blue are the three basic colours of visible light.
