What is the comparative and superlative form of doubtful?

Answer 1

Oh, dude, you're hitting me with the grammar questions now? Okay, so the comparative form of "doubtful" is "more doubtful," and the superlative form is "most doubtful." Like, doubt no more, my friend, you've got it!

Answer 2

Likely, likelier, likeliest. You may also use the Frenchified forms, more likely and most likely. All English adjectives form the comparative in -er. Some snooty people prefer the French form for certain imported or polysyllabic adjectives, thinking that the native English comparatives "sound wrong." But even they must agree that all English adjectives ending in -y take -ier in the comparative.
