Adjective comes onley before the nouns ?

No, adjectives can come before or after nouns. In English, the most common order is for adjectives to come before the noun they modify, such as "red car" or "beautiful house." However, there are also cases where adjectives come after the noun, such as "the car is red" or "the house is beautiful." The placement of adjectives can vary depending on the context and the specific adjective being used.
