lautojen

In Finnish, lautojen is the genitive plural form of lauta, meaning "of boards" or "boards’." Lauta refers to a board, plank, or wooden panel used in carpentry, construction, and crafts. The term is common in technical writing as well as everyday language when discussing materials and inventory.

The genitive plural lautojen is used in noun phrases to express possession, association, or quantity, for example lautojen pituus (the length of the boards) or lautojen valmistus (the manufacture of boards). The singular genitive is laudan, while the genitive plural is laut o jen, i.e., lautojen. The ending -ojen is a typical genitive plural suffix for many -a/-ä nouns, applied to lauta to form laut o jen.

In practice, lautojen appears in inventories, construction and woodworking texts, and descriptive passages about timber. It serves to link the word for boards to other nouns or adjectives in a broader phrase, indicating that the reference is to multiple boards rather than to a single board. As a standard inflectional form, lautojen does not change for number beyond the plural, and it follows typical Finnish noun-declension patterns for -a/-ä nouns.
