ristikkäisissä

Ristikkäisissä is a Finnish adjective form meaning criss-cross, lattice-like, or cross-braced. It is used to describe patterns, structures, or arrangements in which elements intersect each other to form a grid or lattice. The base adjective is ristikkäinen, derived from ristikki or rist—concepts related to a cross or cross-like pattern. Ristikkäisissä is the inessive plural form, used to modify plural nouns in the inessive case (for example, in rakennuksissa, verhoissa, kuvioissa).

The term is common in descriptive and technical language across fields such as architecture, civil engineering, textiles, and design. It conveys a sense of regular crossing or interlacing, whether in physical bracing, decorative motifs, or natural patterns. For instance, one might speak of ristikkäisissä rakenteissa to describe cross-braced supports, ristikkäisissä verhoissa for criss-cross curtains, or ristikkäisissä kuvioissa for lattice-like patterns.

In use, ristikkäisissä typically precedes a plural noun in the inessive, beginning a phrase that specifies where the criss-cross characteristic is observed. The form helps distinguish a feature as being lattice-like rather than simply rectangular or angular. It is one of several related Finnish adjectives formed to describe pattern and texture, alongside other -inen forms that indicate similar attributes in different grammatical cases and numbers.
