Like in the moujér example I gave above, word boundaries are actually very often rather blurry. Minkixän is a conglomerate of minki ("cat, neutral") and the inflected form of the verb xäana ("to happen upon"), which in the first person singular, present tense, is affixed to the object, to form minkixän. Now does that constitue one word? Two?
Moreover, asking for a concise, universal definition of "word" in a room full of linguists is a pretty sure-fire way to start war and strife of epic proportions.
