Phrases:
a) harvest moon, blue moon
c) pencil case, eyebrow pencil, pencil sharpener, thin air.
Phrasal Words:

There is a tin difference between compound words and phrases. Compound words refer to word formation, while phrases refer to the <em>structure of words</em> in a sentence. On the other hand, a phrasal word is a verb formed from the combination of a verb with another <em>part of speech</em>.
Thus, using morphology, which is the <em>study of </em><em>words</em><em>, how they are formed, and their relationship to other </em><em>words </em><em>in the sentence</em>, the words have been grouped accordingly.
