 COMPARATIVES AND SUPERLATIVES

1. We use more.... for adverbs that end in -ly: more slowly, more quietly
2. You can use -er or more... with some two-syllable adjectives, especially: quiet, clever, narrow, shallow, simple
3. IRREGULAR COMPARATIVES:  good/well  >  better, bad/badly > worse, far > further/farther
4. FURTHER & FURTHEST meaning 'more' or 'additional': Let me know if you hear any further news
5. Before comparatives you can use QUANTIFIERS such as: much, a lot, far, a bit, a little, slightly (He's much / slightly taller than his sister).
6. You can use any, no + adjective in the comparative form. Ex. I'm not waiting any longer.
7. Two comparatives of superiority connected by and meaning 'CADA VEZ MÁS'. Ex. The situation is becoming harder and harder.
