henkilölleille

Henkilölleille is not a standard Finnish word. It appears to be a nonstandard or erroneous inflected form rather than an established lexical item. In standard Finnish, the allative case marks direction toward or for someone or something, and its plural form is henkilölle for singular and henkilöille for plural. The form henkilölleille does not appear in standard grammar and is not recognized as a correct inflection.

From a linguistic standpoint, henkilölleille would be analyzed as a mistaken concatenation of the singular allative suffix -lle (henkilölle) with a second allative-like ending -ille, which is not a productive or valid combination in Finnish morphology. Finnish morphology does not typically stack the allative suffix in this way to create a plural-marking form. If encountered, it is usually treated as an error or as a deliberate stylistic or experimental coinage rather than a standard grammatical form.

In usage, readers should rely on henkilölle for “to/for a person” (singular) and henkilöille for “to/for people” (plural). If a text includes henkilölleille, editors or readers are encouraged to interpret it as a mistake and to substitute the standard form. It may also occasionally appear in playful or experimental writing, but it lacks formal recognition in normative language references.
