In a letter bank, the letters of one word are used - and repeated as necessary - to spell a longer word or phrase. In the flat below, EIGHT represents an eight-letter word that is a letter bank. That is, its eight letters are the only ones used to make up the seven-letter and six-letter words represented by SEVEN and SIX.

I used to give to charity
To help my fellow man.
But those gifts are a rarity,
For now it seems I can
Just barely make a living - what
Has changed, you ask? I'll say.
I wed a gal who's lovely but
Spends money every day.
To keep my trophy wife, I've found
Donations I must nix.
Who knew my EIGHT was tightly
   bound
Up with my SEVEN SIX?
