The Three Degrees
Adjectives have three degrees: positive (the base form), comparative (comparing two things), and superlative (comparing one thing to all others).
Comparative: Comparing Two Things
For short adjectives (1-2 syllables), add -er + than. For long adjectives (3+ syllables), use more + adjective + than.
Superlative: One of Many
For short adjectives, add the + -est. For long adjectives, use the most + adjective.
Irregular Forms
Some common adjectives have completely irregular forms.

Degrees of comparison let you grade adjectives: positive (big), comparative (bigger), superlative (biggest). They are essential for describing and ranking things in speech.
Positive, Comparative, Superlative
One-syllable adjectives add -er/-est ('small, smaller, smallest'). Longer ones use 'more'/'most' ('beautiful, more beautiful, most beautiful'). Irregulars include good/better/best and bad/worse/worst. Knowing the form prevents 'more bigger' errors.
Than and The
Comparatives pair with 'than' ('taller than you'); superlatives use 'the' ('the tallest'). 'Of the three' or 'in the class' often follows a superlative. These small words signal which degree you mean.
Common Mistakes
Avoid double comparison ('more better'), and use 'than' not 'then'. 'As...as' shows equality ('as tall as'). Practicing these patterns out loud on SpeakNow fixes them quickly.
Common Mistakes to Avoid
Double comparison is everywhere ('more better', 'most tallest'), along with 'than'/'then' confusion and missing 'the' before a superlative ('tallest boy' should often be 'the tallest boy'). Learners also pick the wrong form for syllable count ('beautifuler' instead of 'more beautiful') and misuse 'as...as' for equality. Knowing one-syllable takes -er/-est while longer words take more/most removes most of the errors.
Try This: A Quick Practice
Compare three things out loud: 'My bag is big, yours is bigger, his is the biggest'. Then with a long word: 'This book is interesting, that one is more interesting, the library copy is the most interesting'. Practise 'as...as': 'My car is as fast as yours'. SpeakNow's degrees-of-comparison exercise repeats correct forms aloud so the syllable rule becomes automatic.
Frequently Asked Questions
What are the three degrees of comparison?▼
Positive (big), comparative (bigger, for two), superlative (biggest, for three or more). Form depends on syllable count and a few irregular adjectives.
When do I use 'more' instead of '-er'?▼
For adjectives of two or more syllables: 'more interesting'. One-syllable words usually take -er/-est. Irregulars like 'good/better/best' must be memorized.
What is wrong with 'more better'?▼
It double-marks comparison. Use 'better' (comparative of good) alone. SpeakNow drills correct forms in speaking exercises.
