syöisi

Syöisi is a Finnish verb form connected to the verb syödä, meaning to eat. It is encountered as a conditional mood form in certain varieties of Finnish, used to express hypothetical action and roughly equivalent to would eat in English. In standard modern Finnish, the usual third-person singular conditional form is söisi; forms such as syöisi occur in older texts, regional dialects, or stylistic uses and may reflect historical vowel alternations or orthographic variation.

Morphology and usage are typical for Finnish conditional forms: syöisi is formed by adding a conditional suffix to the verb stem, with vowel harmony affecting the vowels that appear in the resulting form. Finnish has a full set of conditional forms across the subject persons, such as söisin, söisit, söisi, söisimme, söisitte, and söisivät, which are used in standard Finnish to express hypothetical actions.

Historically, forms like syöisi appear in literary or regional contexts where older inflectional patterns are preserved. They can convey nuance in tone or register, or be used to evoke a traditional or rural flavor in speech and writing. For most contemporary usage, speakers and writers default to söisi for the third-person singular conditional.
