matkustajaisilla

Matkustajaisilla is a form that is not widely recognized as standard Finnish. In contemporary usage, the common adessive plural of the noun matkustaja (passenger) is matkustajilla, meaning on or at the passengers or with the passengers. The spelling matkustajaisilla does not appear in major dictionaries and is generally regarded as nonstandard, a misspelling, or a dialectal/creative variant rather than a mainstream grammatical form.

Linguistic note and interpretation:

Finnish nouns form the adessive plural by adding -lla to the plural stem. For matkustaja, the standard plural is matkustajat, and the adessive plural is matkustajilla. The appearance of an –ais- sequence in matkustajaisilla does not align with the regular inflection pattern and may indicate a typographical error, a regional variation, or a purposeful stylistic choice in a specific text. Without clear context, matkustajaisilla should be treated as nonstandard, and readers are advised to rely on matkustajilla when aiming for correct Finnish.

Usage guidance:

If you encounter matkustajaisilla in a text, consider whether the author intended the standard form matkustajilla or perhaps a different word such as matkustajaiset (hypothetical or historical) or another noun entirely. In most formal writing, matkustajilla is the appropriate choice.

Example:

Matkustajilla oli paljon tavaraa. (The passengers had a lot of luggage.)
