Explanation:
The task involves identifying proper nouns among a list of words where all except one are proper nouns. Proper nouns are specific names of persons, places, or things that begin with capital letters. In this exercise, the odd word in each group is the one that is not a proper noun. For example, 'boy' in the first group is the odd word as it is a common noun while the others are proper nouns.
