1. Suffix.  Denotes the past participle form when attached to a verb.
2. Suffix.  Can be used to denote the plural form of a small number of English words, the majority of whose etymology goes back to the N-stem (i.e. Weak noun) declension of Germanic languages.
3. Suffix.  When attached to certain adjectives, it formed a transitive verb whose meaning is, ''to make (adjective)''. Usually, the verb is ergative, sometimes not. The same construction could also be done to certain (fewer) nouns, as, ''strengthen'', in which case the verb means roughly, ''to give (noun) to''.
4. Suffix.  Suffix meaning "pertaining to", "having the qualities of", "like".
5. Suffix.  When attached to certain nouns that are the names of a material, it forms an adjective whose meaning is, ''made of (noun)''. This is a formative pattern with many obsolescent remnants. Changes in the form of the root noun, and the dropping of the "e" in the suffix occur. There are also orphan formations whose root has been lost to the current language.
6. Suffix.  Used to form the diminutives of certain nouns.
