If you want a clear definition, ask a mathematician:

A word is any written product of group elements and their inverses.

Or a computer scientist:

A word is a fixed-sized datum handled as a unit by the instruction set or the hardware of the processor.

i wonder what the inverse of the letters in the english alphabet are. since it has a non-prime number of letters (26 to be exact), we know that some letters won’t have inverses. i wonder which letters don’t have inverses. i guess it would be pretty easy to find out if you use the standard alphabet ordering and then port the alphabet over to ℤ/26ℤ, but that’s not a particularly satisfying answer.
