Do an adjective come before the noun it modifies?

Yes, in English, adjectives usually come before the noun they modify. This is called attributive adjective order.

Example:

* Beautiful flower

* Red car

* Happy child

However, there are some exceptions to this rule:

* Predicative adjectives come after the noun and are linked to it by a linking verb (e.g., "The flower is beautiful").

* Some adjectives can be placed after the noun for emphasis (e.g., "A problem serious").

* Certain nouns can take adjectives after them, especially in technical or specialized language (e.g., "a room single").

Overall, the most common placement for adjectives is before the noun they modify.
