Comparatives compare two things ('bigger', 'more interesting'); superlatives say which is the most ('biggest', 'most interesting'). We use -er/more for comparatives and -est/most for superlatives. They're very common in everyday speech.
Short adjectives: -er/-est (big, bigger, biggest). Long adjectives: more/most (interesting, more interesting, most interesting). Irregular: good–better–best, bad–worse–worst. Practising in real sentences with Rozy fixes forms and helps you avoid double comparatives ('more bigger').
We use them to compare options, give opinions, or describe ('This is better', 'That's the most important point'). Conversation practice with feedback builds confidence.
