leluisiin

Leluisiin is a Finnish-language word that functions as an illative plural form of the noun lelu, meaning toy. In Finnish grammar, the illative case expresses motion toward or into a destination, and its plural form is used when referring to multiple objects. The term leluisiin is discussed in linguistic descriptions as one possible attested variant of the illative plural for this stem, though it is less common in contemporary standard Finnish.

In everyday Finnish, the standard illative plural formed from lelu is typically leluihin. Leluisiin may appear in dialectal speech, historical texts, or poetic contexts where speakers or writers preserve older phonological patterns or aim for particular rhythmic or rhyming effects. The use of leluisiin thus reflects broader patterns of how Finnish noun stems interact with illative suffixes and vowel harmony across dialects and registers.

Lelu as a word itself is common in Finnish, referring to playthings or toys used by children. The illative plural form, including leluisiin in some varieties, is one piece of the broader Finnish case system, which marks grammatical relations through suffixes rather than prepositions. The choice between leluiin variants and the standard leluihin depends on regional norms, formality, and stylistic considerations.
