lisätyyn

Lisätyyn is an inflected form of the Finnish adjective lisätty, meaning "added" or "supplementary." In standard Finnish, the illative singular form of lisätty is lisättyyn. The form lisätyyn, which lacks the second t, is often encountered as a nonstandard variant or a typographical error in informal writing. The distinction matters in formal contexts, where lisätty with the illative ending is the prescribed form.

Grammar and usage: Finnish adjectives agree with the noun they modify in case and number. When the noun is in the illative case, the corresponding illative form of an adjective like lisätty is typically lisättyyn. This construction is used to denote movement toward or placement into something that has been added, such as sections, texts, or items that have been included in a larger whole. Common targets for such phrases include words like osio (section), teksti (text), and kohde (object).

Examples:

- Lisättyyn osioon on tehty korjauksia. (There are changes made to the added section.)

- Lisättyyn tekstiin on lisätty täydennystä. (Additional content has been added to the added text.)

Notes: Lisätyyn is primarily relevant in Finnish grammar discussions and editing contexts. When reporting or editing, it is important to use lisättyyn rather than lisätyyn to preserve standard spelling and grammatical correctness. The underlying concept—describing something that has been added—remains clear regardless of the specific illative form.
