That says more than you intended.
I think you are confusing prudery for priggery.
Prudery comes from prudent:
prig :1. Careful or wise in handling practical matters; exercising good judgment or common sense: a prudent manager of money.
2. Characterized by or resulting from care or wisdom in practical matters or in planning for the future: a prudent investment.
One who is careful to use the least ambiguous language they can, without intentional obfuscation, offense, or crudity is a prude.1. A person who demonstrates an exaggerated conformity or propriety, especially in an irritatingly arrogant or smug manner.
One who insists others only use academically accepted or approved jargon is a prig.
