Aggravation

in pleading, is the introduction of matter in the declaration which only tends to increase the amount of damages, and does not concern the right of action itself.

Steph. Pl. 257; 12 Mod. 697.

An example of which is found in the case where a plaintiff declares in trespass for entering his house, and breaking his close, and tossing his goods about, the entry of the house is the principal ground and foundation of the action, and the rest is only stated by way of ageravation, 3 Wils. R. 294; and this matter need not be proved by the plaintiff or answered by the defendant.
