I'm trying to figure out how comparatives/superlatives/equatives of adjectives work. I know that in English, there are five possibilities: (1) some adjectives just add the -er and -est endings (e.g. long, longer, longest), (2) some adjectives have a slightly modified stem and the endings (e.g., big, bigger, biggest), (3) some are compared irregularly (e.g., good, better, best) (4) others are only compared periphrastically (e.g. comfortable, more comfortable, most comfortable), (5) still others are not compared at all (e.g., quite). Welsh has the same possibilities, and I'm trying to work out some examples. It's easy to find lists of those Welsh adjectives that fall into category 3 above, so I'm most concerned with 1, 2, 4, and 5. In the list below, I've indicated adjectives from categories 1 and 2 by the notation [stem- &adj] where the &adj stands for adding the normal adjectival endings (-ach, -af, -ed). The absence of such notation is intended to indicate that the adjective is in categories 4 or 5. So I'm worried about 3 kinds of errors in my classification: 1. Do I have notations for adjectives in categories 4 and 5? 2. Am I missing notations for adjectives in categories 1 and 2? 3. Do I have any stems wrong?
