ajalooliseks

Ajalooliseks is the translative form of the Estonian adjective ajalooline, meaning historical. It is used to express a change of state into a historical condition or to describe something as being used in or treated as history. In practice, it often appears with verbs that denote becoming or transformation, such as muutuma or saama.

Usage-wise, ajalooliseks typically marks a transition or function: something can become historical, or be regarded as a historical entity or source. It is common in formal or written Estonian, including historical writing, journalism, and academic contexts. The form answers the question “into what state?” by indicating that the subject is now to be considered historical.

Examples of usage:

- Sündmus on saanud ajalooliseks. (The event has become historical.)

- Dokument on ajalooallikas. (The document is a historical source.)

- See vaatepunkt võib toimida ajalooliseks tõendiks. (This viewpoint may serve as a historical evidence.)

Etymology and related forms:

Ajalooliseks is formed from the stem ajalooline (historical) plus the suffix -seks, which marks the translative case in Estonian. Related forms include ajalooline (historical) in other cases and number forms, as well as phrases like ajalooallikas (historical source) used without the translative ending.

- ajalooline

- allikas

- muutuma

- saama

Note: While ajalooliseks is common in formal contexts to express a change into a historical state, more everyday references often use straightforward adjective forms or compounds, such as ajalooallikas or ajalooline.
