Posed last night in pub. What is a 9 letter word which if you take one letter away at a time always makes a proper word? Last letter left is going to be either i or a but as a clue my friend thought it was i. I got as far as going along the lines of....i, in, sin, spin then fell asleep!
Oh, dear! Word on the street is that you can't move the position of the letters so the previous answers don't work, sorry. This makes task much harder.
Thanks Muriel, that's a good one! Works perfectly, now all I've got to do is convince them at pub that I thought of answer myself. They'll never beleive it! Better give AB the credit.
