List of some often used adjectives

Definition

An adjective is a word which qualifies a noun; e. g.: კარგი მეგობარი k'argi megobari, good friend.
In Modern Georgian the adjective precedes the noun; e. g.:
 

Declension

When an adjective and a noun are inflected together, the noun is declined, whereas adjectives (attribute) with the consonantal stems are declined partly (Table 1).
Adjectives (attribute) with the vocalic stems are not declined and do not change their form at all (Table 2).
All adjectives remain in the singular when noun is in the plural.

 
More detailed about adjectives (attribute) with the consonantal stems (stems ending in a consonant, e.g. didi 'big)
When a consonantal adjective and a noun are inflected together, both adjective and noun take case markers in the nominative, ergative and vocative cases:

did-i saxl-i (big-nominative house-nominative)
did-ma saxl-ma (big-ergative house-ergative)
did-o saxl-o (big-vocative house-vocative)

In all other cases the rule is that

Adjectives (e.g. დიდი did-i) in the dative (დიდ სახლს did saxl-s) and in the adverbial (დიდ სახლად did saxl-ad)  are usually considered to be a form of dative (and adverbial) where the case marker is omitted.

Degrees of comparison
Adjectives have degrees of comparison. There are the following degrees of comparison in Georgian:

• The positive degree - this is a neutral, initial form of the adjective that expresses a property, characteristic, or feature of a thing, e. g.: დიდი didi big.
• The comparative degree - expresses a higher degree of a property than the positive degree, e. g.: უფრო დიდი upro didi bigger.
• The superlative degree - expresses the highest degree of a property, e. g.: უდიდესი udidesi the biggest.

• "A little bit" degree. It indicates a feature in lower degree than is denoted in the positive degree. In Georgian grammars its name is ოდნაობითი, which can be translated as "a little bit" degree or "to a slight" degree, e. g.: მოდიდო modido a bit big.

The comparative degree is formed by adding the postposition -ze -ze -on to that noun which is represented as an object of comparison. e. g.:
 

It is possible to express the same meaning with another construction as well:
უფრო - ვიდრე  upro - vidre  "more - than", e. g.:
 

The superlative degree
This degree is usually expressed by means of adding the word ყველაზე q'velaze (more than any):
 

The superlative degree may also formed by adding the prefix უ- u- and the suffix -ეს -es to the stem of the positive degree, e. g.:

The "little bit" degree
This degree is formed by adding the prefix mo- mo- and the suffix -o -o to the stem of the positive degree, e. g.:
 

Initial and derived adjectives
Initial (original) adjectives

The stem of an initial (original) adjective is an undividable morpheme. e. g.:
დიდი didi big
პატარა p'at'ara small, little
შავი shavi black etc.

Initial (original, non-derived) adjectives are able to form the degrees of comparison described above.
By adding affixes (prefixes and suffixes) new adjectives may be formed from the initial adjectives. Adjectives formed from other adjectives and nouns are called derived adjectives.

Derived adjectives

Derived adjectives express the property or feature of a thing in relation to another thing. They are derived from nouns or other parts of speech by adding affixes, e. g.:
 

ქუდ- kud- is a root; The root + all other affixes presented in the word (except the case marker) make a stem; e.g.:

ქუდ-იან-ი:
ქუდ- is a root.
ქუდ-იან-  is a stem, and consists of the root kud- and the suffix -ian.
-ი is the nominative case marker.

უ-ქუდ-ო:
ქუდ is a root.
უ-ქუდ-ო is a stem, and consists of the root -ქუდ-, the prefix u- and the suffix -o.
The nominative case marker is not presented because the stem is ending in the vowel.
Nom. უქუდო-ø (no nominative marker, if it had been presented, it would have been  უქუდო-ი)
Erg.უქუდო-მ
etc.

comp:
Nom. ქუდიან-ი the stem is ending in the consonant -n -n (kudian-), the nominative marker is -i.
Erg. ქუდიან-მა
etc.

Derived adjectives usually are not able to form the degrees of comparison.

Among other derived adjectives, it would be interesting to touch upon adjectives expressing the origin of a person or a thing.
The suffixes -ელ -el and -ურ -ur(/-ულ -ul) produce the adjectives of origin as follows:
The suffix -el is used if an adjective refers to human beings (group who), and the suffix -ur is used for adjectives referring to everything else (except human beings), including both animate and inanimate objects (group what):

ბოლნისელი ექიმი Bolnis-el-i ekimi doctor from Bolnisi
ბოლნისური პური Bolnis-ur-i p'uri bread from Bolnisi
ბოლნისური ქათამი Bolnis-ur-i katami a hen from Bolnisi
