The words in each row of this puzzle have something in common: all can be joined with another word to produce compound words or well-known word pairs. FULL, HARVEST, and HONEY, for example, can combine with MOON to make FULL MOON, HARVEST MOON, and HONEYMOON. Finding these common words for each row gives us the following list:
The third row could feasibly be either SCHOOL or GROUND, introducing a small ambiguity. As these answer words form new sets of triplets, our first instinct is to repeat the process. (This eliminates the ambiguity in the third row, as only SCHOOL leads to a good answer.)
OLD (OLD BOY, OLD HAT, OLD SCHOOL)
NEW (NEW MOON, NEW WAVE, NEW YEAR)
BORROWED (BORROWED CHORD, BORROWED TIME, BORROWED WORD)
BLUE (BLUE CHEESE, BLUE CHIP, BLUEGRASS)
The fifth triplet, however, doesn't seem to fit this pattern, as suggested by the italicised clues. The four answers we do have bring to mind the famous wedding rhyme "Something old, something new, something borrowed, something blue" which is fitting for a puzzle about the marriage of words. The last line of this rhyme is "and a sixpence in her shoe." The "blank in shoe" referred to by the last line, then, is SIXPENCE, yet another compound word.
|The answer is: sixpence|
