Good Night!!!

In English, Adjectives are placed in front of the noun.  For example, "He is a happy person".  

The exception occurs with stative verbs or non-doing or non-action verbs, which are typically placed at the end of a sentence.  For example, "He is very tired". That is referred to as a "state of being".
