One possible answer is heaven. (Another is seal.) The words all go with numbers:
first aid
second-guess
third degree
fourth estate
Fifth Avenue
sixth sense
seventh heaven / seventh seal
You could create other puzzles with the same premise:
amendment
hand
world
dimension
wheel
Of course, all of those could be amendment, or the first three of them could be base or degree or estate or world. But in most of the above cases I think the numbers given are the numbers most commonly associated with the given words.
You could also do a silly version of the puzzle:
yousayyoudoandthenyoudon't
themotion
time'sthecharm
forbridge
ofwhiskey
But somehow I think it would be easier to guess the answer to that version.
