Hello, fellas. In this session we will learn predicate adjectives.
According to Betty Schrampfer Azar, adjectives are words describing nouns. They are usually placed right before nouns. An adjective can also follow a linking verb such as be, feel, look, smell, sound, taste, appear, seem, and become.
(More on linking verbs: https://englishtips4u.com/2011/08/23/engclass-linking-verb/ and https://englishtips4u.com/2012/03/12/engclass-linking-verbs/)
However, several adjectives only occur after linking verbs and they cannot come directly before nouns they describe. A predicate adjective should be changed into its corresponding form to use in front of a noun.
Here are predicate adjectives and their corresponding forms:
alike= like similar
alive= live living
1) The two brothers look alike.
2) We completed our projects in a similar manner.
3) The girl is afraid of heights.
4) The frightened child cried for his mother.
