Superlative adjectives show the highest or lowest degree of a quality in a group. We use them when one person, thing, or place is different from all others in the same group. They often come before a noun or after a verb such as be.

We usually use the with a superlative adjective. This shows that we talk about one thing as the top or bottom member of a group. The group may be named in the sentence, or it may be clear from the situation.

Many short adjectives make the superlative with -est. This pattern is common with one-syllable adjectives and with some two-syllable adjectives. The ending is added to the adjective, and we usually use the before it.

Verb	Form
small	smallest
long	longest
cheap	cheapest
happy	happiest

Some adjectives change their spelling before we add -est. These changes follow regular spelling patterns. The pronunciation of the base adjective usually stays close to the original word.

Many longer adjectives make the superlative with most. This pattern is common with adjectives of two or more syllables. In careful English, this is the usual form for many long adjectives.

Verb	Form
beautiful	most beautiful
important	most important
comfortable	most comfortable
interesting	most interesting

Some adjectives do not follow one simple pattern. A few two-syllable adjectives can take either the -est form or most, and style can affect the choice. Native speakers do not always agree on every adjective, so some variation is normal.

Region	Word or Phrase	Regional Definition
General English	commonest and most common	Both forms are used, and commonest is often more formal or literary 📘.
General English	narrowest and most narrow	Both forms exist, but narrowest is often more usual in everyday English 🗣️.
General English	politest and most polite	Both forms are possible, and speakers may choose by style or rhythm 🎵.

Some adjectives have special superlative forms. These forms do not use -est or most in the usual way. They must be learned as separate words.

Verb	Form
good	best
bad	worst
far	farthest and furthest
little	least

You can now use superlative adjectives to show the highest or lowest degree of a quality in a group. You can choose between -est forms and most forms, use the with superlatives, and recognize regular, irregular, and variable patterns. You can also understand that some forms vary by style or speaker choice.
