inenpäätteiset

inenpäätteiset refers to a productive class of Finnish adjectives that end with the suffix -inen (with variants such as -äinen or -äin- depending on the stem). They are typically formed from nouns or other stems to express a property, material, or characteristic of the noun they modify. The name of the class comes from the common -inen ending.

Formation and morphology: The suffix attaches to various stems to produce adjectives, and the ending adjusts to follow vowel harmony. Common examples include sininen (blue), punainen (red), valkoinen (white), and keltainen (yellow). The word puinen (wooden) is another familiar instance. These adjectives behave like other Finnish adjectives in their inflection, agreeing with the noun in number and case and appearing in attributive and predicative positions.

Usage: In sentences, -inen adjectives can describe color, material, or inherent properties. They can occur before a noun (attributive) as well as after a linking verb (predicative), as in talo on punainen (the house is red) or punainen talo (a red house). They also participate in normal adjective inflection, forming plural forms and the appropriate case endings.

Notes: The -inen suffix is a productive derivational tool in Finnish, but not all stems admit an -inen form. The suffix exists alongside other derivational endings, and some stems yield irregular or less common forms. The class provides a clear, recognizable way to form common descriptive adjectives, especially for colors and materials, and it illustrates the general pattern of Finnish noun-to-adjective derivation.
