なadjectives are often used to introduce foreign words and new concepts. For example, “handsome” is English, but part of speech is an adjective. Therefore, in order to be recognized as an adjective in Japanese, the adjective is called “ハンサムな（なAdj）”.
In addition, many nouns can be adjectives by connecting suffixes such as “Nらしい（N-like）” and “Nっぽい（N-ish）” to a noun for an original noun [N]. Also, adjectives have the feeling that they are more emotional words.
The following are typical grammars for changing nouns to adjectives and adjectives to verbs, etc.
(1)い Adjective ⇨ noun
Nouns are formed by adding “さ” to the stem of an いadjective to indicate “being a degree”.
(2) いAdjective ⇨ verb
By changing the ending “い” of the subjective いadjective expressing sensation / emotion to “がる”, a verb meaning “action expressing that feeling” is created.
(3) いAdjective ⇨ verb
Verbs are formed from some adjectives.
Ex. たのしい（いAdj)⇨たのしむ(Vi: intransitive verb)
たかい⇨たかまる(Vi: intransitive verb)・たかめる(Vt: transitive verb)
(4) Verb ⇨ adjective
Adding “しい” to the verbないform, the meaning is changed to “I feel like doing that.”, which is いadjective.
◆ Order of adjectives
Now, let’s consider the order of adjectives. If you want to modify a single noun with multiple adjectives, what is the order?
English adjectives have the following word order when modifying nouns. This restriction on word order in English is quite restrictive
a nice big red old Italian leather-shoes
[Subjective judgment] / [Scale] / [Color] / [New / Old] / [Affiliation] / [Material] + Noun
On the other hand, in the case of Japanese, such restrictions on the word order are loose. Broadly speaking, they tend to be arranged in the following order.
いろいろな すばらしい あたらしい けいけん
[Type / Quantity] ・ [Subjective evaluation] ・ [Attribute (large and small, old and new, color, etc.)] + Noun
The content you want to convey tends to be closer to a noun.
