Usage Notes & Examples:
- Conjugating to the causative form results in the creation of a new ichidan verb (even if the starting verb was godan). This resulting verb can be conjugated to give negatives, past tenses, presumptives, provisionals, polite forms, etc., just as any other ichidan verb. Of course, you must be careful, as there are conjugations that wouldn't make logical sense for a verb in the causative form.
