(n.) A contrasting force or impulse of any kind; as, the pressure of poverty; the pressure of taxes; the pressure of motives on the mind; the pressure of civilization.
(n.) Affliction; distress; grievance.
(n.) Urgency; as, the pressure of business.
(n.) Impression; stamp; character impressed.
(n.) The action of a force against some obstacle or opposing force; a force in the nature of a thrust, distributed over a surface, often estimated with reference to the upon a unit's area.
