Ilmentäisi

Ilmentäisi is a Finnish verb form used in conditional mood. It represents the third-person singular form meaning “he/she/it would ail” or, more broadly, “would manifest” depending on the base verb it is derived from. In standard Finnish, ilmentäisi is the third-person singular conditional ending -isi added to the stem ilmentä- or to a closely related root such as ilmentä- in ilmentää (to reveal or to manifest) or ilmentyä (to become apparent or to fall ill). The exact meaning depends on which verb is intended.

Grammatically, ilmentäisi follows the regular Finnish conditional paradigm, sharing its ending with other -isi forms like sanoisi (he/she would say) and tekisi (he/she would do). The stem may undergo standard vowel harmony and minor phonological adjustments typical of Finnish verb conjugation.

Usage and nuance, in practice, center on hypothetical or polite statements. It is used when describing an action that would occur under a condition or in reported speech about someone’s potential behavior. For example: “Jos hän ilmentäisi oireita, hänen tulisi hakeutua lääkäriin” translates to “If he would exhibit symptoms, he should seek medical advice.” The sense can also be extended to “would manifest [signs]” in contexts discussing diseases or symptoms, depending on the intended meaning of ilmentä-.

Related noun forms include ilmentäminen (the act of manifesting or showing) and ilmentymä (manifestation or appearance). In medical or health contexts, ilmentyminen is sometimes used to refer to the emergence or appearance of symptoms.
