The commonest adjectival suffix is -ise (nominative -inen), which is added usually to nouns. Aamu, morning, aamuinen, early; kulta, gold; kultainen, golden. This suffix is sometimes added to cases, especially the essive; yksinÄinen, ominainen, luonteinen. Similarly the very common suffix -llise (nominative -llinen) is the result of adding ise to the adessive or allative—maallinen, rahallinen, vihollinen.

-ttoma (nominative ton) is a caritive suffix signifying without or deprived of (cf. the English -less); isÄtÖn, fatherless; rahaton, moneyless. It is frequently added to the third infinitive of verbs, e.g. kuolematon, immortal.

-kkaha (nominative -kkas) is the exact contrary of this last suffix, and signifies progressing or provided with; rahakas, having much money; voimakas, strong.

-isa and -va have much the same meaning as -kkaha; kuuluisa, glorious; kalaisa, rich in fish; lihava, fat; terÄvÄ, sharp.

-se, -kaise, and -hka, -hko are used to form adjectival diminutives; lyhykÄinen, short (Russian ???????????), pitkÄhkÖ, longish.

The suffix -mainen forms adjectives meaning like, or rather; English -ish; lapsimainen, childish; poikamainen, boyish; hyvÄmÄinen, pretty good.
