Diminutive

Diminutive is a term for a special type of nouns the meaning of which can be characterized as SMALL N (where N is the predicate denoted by the noun).

Example
Dutch diminutives are formed by adding one of the allomorphs of the suffix -tje (viz. -pje, -kje, -etje, -je, -tje) to nouns. (i) gives a number of relevant examples:

(i) raam	'window'	raam-pje	'small window' koning	'king'		koning-kje	'small king' pan		'pan'		pann-etje	'small pan' hok		'cage'		hok-je		'small cage' baan	'job'		baan-tje	'small job'
