diaesitysten

Diaesitysten is the genitive plural form of the Finnish noun diaesitys, meaning slide presentation. It is used to indicate possession or relation to multiple slide presentations, as in phrases like diaesitysten laatiminen (the preparation of slide presentations) or diaesitysten käyttö opetuksessa (the use of slide presentations in teaching). The corresponding nominative plural is diaesitykset.

Etymology and usage: The first element dia- refers to photographic slides (dia) in Finnish, a loanword from earlier European usage, while esitys means presentation. The combination diaesitys denotes a sequence of slides designed to be displayed during a talk or lecture. In modern Finnish, diaesitysten tends to appear in genitive constructions such as diaesitysten muokkaaminen (modification of slide presentations) or diaesitysten sisältö (the content of slide presentations).

History and context: The concept originated with the use of slide projectors and photographic transparencies from the mid-20th century through the late 20th century in education and business. Traditional diaesitys consisted of physical slides projected onto a screen, often accompanied by narration. With digital technology, diaesitykset today are typically digital slide decks created with software like PowerPoint or Keynote, though the historical term and its inflected forms remain in use in Finnish.
