 * Adjectives

Adjectives are words that add description to a person, place, thing, or idea.

For example:
 * Reykjavík is beautiful.
 * Cars pollute, but are essential.
 * When you are sad, think of good memories.

In Icelandic, these take on endings and inflections like verbs and personal pronouns do in English.

Case, gender, and number
In Icelandic, adjectives are inflected for gender and case. Most Icelandic dictionaries will give the masculine form of the adjective by default. Adjectives usually end in "-ur" in the masculine nominative.

Strong vs. weak adjectives
Case, gender, and number are not the only ways that adjectives are declined in Icelandic.

The strong form of an adjective is used when its meaning is not modified by the definite article, while the weak form is used when the meaning is modified. Examples:
 * svart ur kött ur 
 * a black cat".

Here, the definite article is not used at all, so the adjective would be in the strong form.
 * svart i kött urinn 
 * "the black cat".

Here, the adjective is used to say which cat the speaker is referring to, not to provide additional information. Therefore, the weak form of the adjective is used.
 * Kött urinn er svart ur .
 * "The cat is black.".

Here, even though the noun is in the definite, the adjective's meaning is not changed by the definite article, so the strong form is used.

Inflection
The inflection table above shows the strong forms of the adjectives. This is how adjectives are declined in the weak form.

Comparative and superlative adjectives
In Icelandic, as in with most other languages, adjectives have a positive, comparative, and superlative degree. Examples:
 * My car is bigger than yours. (comparative)
 * Reykjavík is the largest city in Iceland (superlative)

Inflection
The comparative does not have separate strong/weak forms.

Forming adjectives from nouns or verbs
-legur (cognate with English "-like") is the most common suffix added to a noun or verb to form an adjective. Examples:
 * persónu legur  : personal.
 * from persóna : person.
 * haust legur  : autumnal.
 * from haust : autumn.
 * beygjan legur  : bendable.
 * from beygja : to bend.
