USAGE
When the adjective worthwhile is used attributively （i.e. before the noun） it is always written as one word: a worthwhile cause. However， when it is used predicatively （i.e. it stands alone and comes after the verb） it may be written as either one or two words: we didn't think it was worthwhile/ worth while.
