What exactly is a word ?

Hello people,
What exactly is a word ?
I know a word is basically a unit and i know the word=2 bytes on an x-86 processor.
But is the word size the same on an Itanium Processor as well ?
I feel 1 word = 2bytes(x86)
= 4bytes(32 bit system)
= 8bytes(64 bit system)
That is the word size ,is always taken such that [b]The size of a pointer is always equal to 1 word[/b]

Please clarify
