exceptions to one-syllable adjectives ending in a consonant

[Vladv1]

I know that for one-syllable adjectives ending in a consonant + y (like shy, dry, change the final y to i and add -er or -est, for exampe; shy → shier, shiest; dry → drier, driest
The adjecitve "coy", though, ends in consonat and + y , and changes differently-coy-coyer-the coyest.
Could you please provide more such exceptions?

So, do you view "o" as a consonant rather than a vowel? How is it that you find "coy" an exception to the rule?

Yes, you are right. I meant, is there an exception to the rule when one-syllable adjectives ending in a consonant + y (like shy, dry, change the final y to i and add -er or -est)?

shy → shier, shiest

There's one right there—it ought to be shy → shyer, shyest
