postauksessa

Postauksessa is a Finnish word formed from the noun postaus (a post, posting) in the inessive case, literally meaning "in the post" or "inside the post". It is commonly used in spoken and written Finnish to refer to the content contained within a single entry on a social media platform, blog, forum or other online publishing medium. Typical usage: "Postauksessa kerroin kokemuksistani" ("In the post I described my experiences").

The base word postaus is a relatively recent loanword and neologism derived from English "post" via Finnish verb forms such as postata (to post) and the noun-forming suffix -aus. Postauksessa is the singular inessive form; related case forms include postauksesta (elative, "from the post") and postauksissa (plural inessive, "in the posts").

In practical contexts, postauksessa often introduces summaries, references to specific content elements (images, links, comments) or commentary about the post itself. It appears across platforms (e.g., Facebook, Instagram, X, blogs) and in journalistic or conversational descriptions of online activity. Usage is informal to neutral and widely understood among Finnish speakers familiar with digital communication.
