Going to pile on to the agreement here -- for example, much confusion can be had when discussing things like "intentionality" with laypeople. Philosophy is riddled with regular words that take non-regular meanings. It might make philosophers feel smart, but it's a detriment to the field imo.

Much, though not all, of this is due to philosophers discussing ideas from the past three thousand years originally in a multitude of languages. How should one discuss a "Platonic Idea" without confusion of a general idea?
