Usage notes

• Usually appended to the genitive or nominative singular stem.
• Place names already ending in -la often do not duplicate the suffix, and their adjective forms may be formed with simply -inen (e.g. Karjala → karjalainen, not ˣkarjalalainen).

Etymology 2

From compounds with laji ‎(“kind, sort”) +‎ -inen. The origin as a separate word can still be seen in the imperfect accommodation to vowel harmony.

Suffix

-lainen

1. Combined with a pronoun, forms an adjective relating to the kind or nature of a person or an object.

   eri → erilainen = different

   eräs → eräänlainen +subst. = kind of a + subst.

   mikä → minkälainen or millainen = what kind of?

   sama → samanlainen = similar, of the same kind

   se → sellainen = such, of that kind

   tämä → tällainen = of this kind

2. Combined with the genitive form of an adjective, forms an adjective indicating a smaller degree of the quality than that described by the original adjective.

   heikonlainen = relatively weak

   oikeanlainen = of a right kind (but not the right one)

   viileänlainen = sort of cool

Usage notes

As this suffix is historically a compound, it is not subject to vowel harmony in the standard language; with the exception of the word yhtäläinen, it always has back vowel harmony. In colloquial use it may have a front vowel variant, however.
