Augmentative
An augmentative (abbreviated AUG) is a morphological form of a word which expresses greater intensity, often in size but also in other attributes. It is the opposite of a diminutive.
Since overaugmenting something often makes it grotesque, in some languages augmentatives are used primarily for comical effect or as pejoratives.
Many languages have augmentatives for nouns; some have augmentatives for verbs.
Germanic languages
English
In modern English, augmentatives can be created with the prefixes:
over-: e.g., overlord and overseer.
grand-: e.g., grandmaster and grandparent.
super-: e.g., supermarket and superpower.
mega-: e.g., mega store and megastar.
arch-: e.g., archrival and archangel.
Since the early 1990s, the prefix über- has also frequently been used as a borrowing from German. The suffix -zilla, expressing a monstrous quality, can also be considered an augmentative form.
Dutch
In modern Dutch, augmentatives are usually created with the prefixes:
over-: e.g., overgewicht and oververhitting (resp. "overweight" and "overheating")
