Muttereihin

Muttereihin is a Finnish grammatical form used to indicate direction toward or into more than one nut (hardware nut). It is the illative plural form of mutteri, the word for a threaded fastener nut. In Finnish, illative case marks into or toward, and the plural indicates multiple items.

Formation: The base noun mutteri becomes mutterit in the nominative plural. The illative plural is formed by adding the suffix -eihin to the stem, with adjustments for vowel harmony and consonant gradation as required by standard Finnish spelling rules. The result muttereihin is used when the action is directed toward or into several nuts, such as in assembly instructions or technical descriptions.

Examples: - Ruuvit kiristetään muttereihin. (The screws are tightened into the nuts.) - Aseta aluslevyt muttereihin ennen ruuvien asennusta. (Place the washers toward the nuts before installing the screws.)

Usage notes: Muttereihin is common in technical, mechanical, and instructional contexts where multiple nuts are involved. It contrasts with singular illative forms like mutteriin (into the nut) and nominative mutterit (the nuts). Understanding muttereihin helps with precise directional phrases in Finnish hardware discourse.
