Is addictable a word

Answer 1

There are two ways of acknowledging something as a 'word'. If it occurs in a recognised dictionary, then it is a word (this is the easy way). But something which isn't in any dictionary can still be a word, if a large number of natural speakers of a language use it and understand it in their everyday conversation. In the 1970's 'latte' wasn't in any English dictionary; but everybody in Berkeley, and most people in Seattle, knew what a 'latte' was:- so it was a 'word' for them.

There is no mention of 'addictable' in the full text of the Oxford English Dictionary (last print edition):- so most people would not accept 'addictable' as a normal English word.

You can always make a case that any word which fluent English speakers use and understand is a word (whether it is in a dictionary or not): but I don't think you can do that here.

If 'addictable' existed, would it be connected to the modern meaning of addict ('person enthralled by a narcotic substance') or to one of the older meanings(' property patient of entailment, particularly by legal edict').

Since the word isn't in any dictionary I know of, and I can't make out what it means, I don't think you can call it a word.
