How to Form Adjectives

Most Adjectives of one or more syllables form the Comparative Degree by adding "-er"; and the Superlative Degree, by adding "est" to the Positive Degree.

Examples:

Positive Degree	Comparative Degree	Superlative Degree
black	blacker	blackest
bold	bolder	boldest
clever	cleverer	cleverest
deep	deeper	deepest
great	greater	greatest
hard	harder	hardest
kind	kinder	kindest
long	longer	longest
proud	prouder	proudest
rich	richer	richest
small	smaller	smallest
sweet	sweeter	sweetest
tall	taller	tallest
young	younger	youngest

If the Positive Degree ends in "e" only "-r" and "-st" are added to form Comparatives and Superlatives respectively.

Examples:

Positive Degree	Comparative Degree	Superlative Degree
able	abler	ablest
brave	braver	bravest
fine	finer	finest
large	larger	largest
late	later	latest
nice	nicer	nicest
noble	nobler	noblest
simple	simpler	simplest
true	truer	truest
white	whiter	whitest
wise	wiser	wisest

If the Positive Degree ends in "y" preceded by a consonant, the "y" is changed in to "i" while adding "-er" or "-est" to form Comparatives or Superlatives.

Examples:

Positive Degree	Comparative Degree	Superlative Degree
busy	busier	busiest
dry	drier	driest
easy	easier	easiest
happy	happier	happiest
heavy	heavier	heaviest
jolly	jollier	jolliest
merry	merrier	merriest
noisy	noisier	noisiest
pretty	prettier	prettiest
wealthy	wealthier	wealthiest

If the Positive Degree ends in "y" preceded by a vowel, the "y" is not changed while adding "-er" or "-est" to form Comparatives or Superlatives.

Example:

Positive Degree	Comparative Degree	Superlative Degree
grey	greyer	greyest

If the Positive Degree is one consonant preceded by a short vowel, the final consonant is doubled, while adding "-er" or "-est" to form Comparatives or Superlatives.

Examples:

Positive Degree	Comparative Degree	Superlative Degree
big	bigger	biggest
fat	fatter	fattest
hot	hotter	hottest
mad	madder	maddest
red	redder	reddest
sad	sadder	saddest
thin	thinner	thinnest
wet	wetter	wettest

All the Adjectives of more than two syllables (and some of two syllables also) form the Comparative Degree by adding "more" and the Superlative, by adding "most".

Examples:

Positive Degree	Comparative Degree	Superlative Degree
beautiful	more beautiful	most beautiful
courageous	more courageous	most courageous
difficult	more difficult	most difficult
industrious	more industrious	most industrious
learned	more learned	most learned
proper	more proper	most proper
satisfactory	more satisfactory	most satisfactory
useful	more useful	most useful
