viestiin

Viestiin is the illative singular form of the Finnish noun viesti, meaning a message. In Finnish grammar, the illative case marks direction toward or into something, and viestiin specifically indicates movement toward a message or addressing a message as a target. The form is used in contexts where the action is directed at a message, such as replying to or reacting to it.

Morphology and related forms: The illative suffix -in attaches to the stem viesti to produce viestiin. The corresponding plural illative for multiple messages is viesteihin. Other related forms include viestin (genitive singular) and viestit (nominative plural).

Usage and common constructions: Viestiin appears with verbs that designate responding to or interacting with a message. It is common in written and spoken Finnish to say things like vastata viestiin (to reply to the message) or tarttua viestiin, depending on the context. The illative can also appear in questions such as "Vastaatko viestiin?" to ask whether someone will reply to the message.

Examples:

- Vastasin asiakkaan viestiin tänään. (I replied to the customer’s message today.)

- Voisitko vastata viestiin ennen määräaikaa? (Could you reply to the message before the deadline?)

- Hän reagoi viestiin nopeasti. (He reacted to the message quickly.)
