Additioiden

Additioiden is the genitive plural form of the Latin loanword additio, used in Finnish to refer to additions or supplements. The term appears mainly in scholarly, historical, or palaeographic contexts and denotes items that have been added to a base text, list, or document. In textual criticism, additioiden can describe interpolations, marginalia, or later appendices that editors incorporated into a manuscript beyond the original compilation.

In practice, the concept aligns with what in publishing or archiving would be called addenda or appendices. The Finnish language commonly uses native terms such as lisäykset, liitteet, or lisäosat, depending on the context, but additioiden may be encountered in academic writing, editions of historic texts, or translations of Latin sources that retain the Latin terminology.

Usage notes: additioiden tends to occur in specialized or formal Finnish rather than everyday language. It is most likely to be found in discussions of manuscript tradition, cataloging of collections, or the study of textual integrity where scholars refer to elements added after the initial composition.
