What are the comparative and superlative form of the word suitable?

Answer:
The preferred comparative form is more suitable and the superlative form is most suitable.
Suitabler and suitablest are grammatically correct, though they may sound wrong to some people. Abler and ablest are the normal degrees of able. Only the pouty prim insist on "more able."
