Question

I cannot tell which is a predicate adjective:

He looks ill today.

He looks disdianfully at the pile of laundry.

Ill or Disdainfully?

Answer 1

"Ill" is correct; "disdainfully" is an adverb, so it can't be any kind of adjective!

Think of predicate adjectives as words that are describing the subject from the other side of the linking verb.

Here are some examples:

He is tall. ("tall" modifies "He")
The book is old. ("old" modifies "book")

There are some words in addition to forms of the verb "to be" that can be linking verbs -- to seem, to look, etc.
