Answer 2

Для образования сравнительной степени прилагательных, как правило, добавляется окончание "-er". В превосходной степени добавляется "-est". Однако есть исключения, которые требуют изменения корня или написания совсем другого слова. Вот таблица сравнительной и превосходной степени для указанных вами прилагательных:

1. New - newer - newest
2. Old - older - oldest
3. Lucky - luckier - luckiest
4. Big - bigger - biggest
5. Nice - nicer - nicest
6. Young - younger - youngest
7. Good - better - best
8. Sad - sadder - saddest
9. Difficult - more difficult - most difficult
10. Angry - angrier - angriest
11. Warm - warmer - warmest
12. Dry - drier - driest (или dry - dryer - dryest)
13. Grey - greyer - greyest (или gray - grayer - grayest)
14. Effective - more effective - most effective
15. Mad - madder - maddest
16. Short - shorter - shortest
17. Thin - thinner - thinnest
18. Long - longer - longest
19. Pleasant - pleasanter - pleasantest (или pleasant - more pleasant - most pleasant)
20. Stupid - stupider - stupidest
21. Common - commoner - commonest (или common - more common - most common)
22. Polite - politer - politest (или polite - more polite - most polite)
23. Able - abler - ablest (или able - more able - most able)
24. Little - littler - littlest (или little - smaller - smallest)

Заметьте, что в некоторых случаях, особенно при более длинных прилагательных, можно использовать "more" и "most" для образования степеней сравнения и превосходной степени.
