I was reading a book that my friend had lent me and came across a slip of paper that I supposed was a bookmark. Reading it I saw the following:
DAM
GAS
LOS
NET
NIM
TOR
VIC
WED
YAK
Knowing my friend likes word games and puzzles I tried to see what, if anything, connected the words. In the end I gave up and phoned him.
Him: Oh ha, yes that's just a list of words that I was playing with.
Me: Well I can see that. I wondered why you included LOS. That's Spanish isn't it?
Him: Just read me all the words.
I read them down the phone.
Him: Oh no, all the words on that paper are perfectly ordinary English dictionary words.
Me: Are you sure that the name 'VIC' is in the dictionary?
Him: No, I mean I just cut that bookmark from the edge of a larger piece of paper. I obviously cut through the list of words as well. They were originally longer - all were five letters long in fact.
Me: So what were the original words then?
Him: I think you have now have enough information to work that out for yourself.
Me: Are you sure?
Him: Just find what they all have in common.
Question
