Ketjuihin

Ketjuihin is the illative plural form of the Finnish noun ketju, meaning chain. It is used to express movement toward or into multiple chains, or placement into a situation involving several chains. The form can also appear in metaphorical contexts to indicate linkage or sequence.

Morphology and forms: The word is built from the stem ketju- with the illative plural suffix -iin, following Finnish vowel harmony. The corresponding singular illative is ketjuun. Related cases include ketjujen (genitive plural), ketjuissa (inessive plural), and the base ketju (singular). The illative plural ketjuihin specifically marks direction toward multiple chains.

Usage notes: Ketjuihin appears in contexts describing physical movement or placement into chains, for example when objects or persons are directed toward, placed into, or enclosed by several chains. It can also be used more abstractly to discuss networks, sequences, or linked events as a figurative concept. In everyday Finnish, the illative plural is common after numerals or quantities and in constructions that express direction into containers or collections.

Context and register: Ketjuihin is a native Finnish term and tends to occur in technical, industrial, or literary contexts where chains or linked structures are discussed. It is less common in casual speech, where more general phrases for “into the chains” might be preferred.
