Turkish has all last three of these, if I understand what you are talking about...,(reply>), yeah, the problem with the spectrum is that a language can have more than one of the stated word-forming systems. Take Japanese as example. words like 信, 感, 命 can be used alone as a single word (Trust, Feeling, Order/Life), but it can also be extended into verbs, like 信じる,感じる,命じる (to trust, to feel, to order). Different words can also be combined as a different word, like 運 (luck) together with 命 (life), to become 運命 (fate). All verbs and adjectives (some adjectives only) can also be conjugated, like in English, to express negation (信じない), perfective (信じた), imperative (信じろ), or by connecting with other verbs through te-form (信じて), express intent (－てみる), continuity (－ている), favors (－てくれる,－て上げる), direction (－てくる,－て行く), etc. So it basically is both isolated, agglutinative AND fusional.
