In each of the groups of 3 words below, the first and second words make a 2-word phrase; the second and third words also make a 2-word phrase. Easy you might say and you would be right, if it wasn't for the fact that a third constraint requires that the first and third words be related. They may both be transposals, synonyms, antonyms, homophones, heterophones, different tenses of the same verb, palindromes, reversals, mutual shifts, rhyming words, AEIOU words, and so on.
