Aside from subjecting you to some obvious clues, there isn't much I can add, so I'll just give you a picture of the grid & let you figure it out from there.Q: Take the four words "salt," "afar," "lava" and "trap." Write them one under the other, and the words will read the same vertically as horizontally. This is a word square of four-letter words. Note that the only vowel in this example square is an A. The object of the challenge is to create a five-letter word square using only common, uncapitalized English words, in which the only vowel in the entire square is A. The word in the center row, and column, is NASAL.
Edit: "Aside from" = APART, "Subjecting" = things you might study as in PANDA (zoology), DRAMA and ATLAS (geography). The last clue was "& let" since the consonants in "aMPeRSaND LeT" are the ones used in the puzzle.
A: PANDA, APART, NASAL, DRAMA, ATLAS
