Old IrishEdit


From com- (together) +‎ suidigud (putting, placing), a calque of Latin compositiō, itself a calque of Ancient Greek σύνθεσις (súnthesis).


  • IPA(key): /ˈkoṽhuðʲiɣuð/


comṡuidigud m (genitive comṡuidigtheo)

  1. verbal noun of con·suidigedar
  2. (linguistics) compounding, composition (formation of compound words from separate words)
    • c. 845, St. Gall Glosses on Priscian, published in Thesaurus Palaeohibernicus (reprinted 1975, Dublin Institute for Advanced Studies), edited and with translations by Whitley Stokes and John Strachan, vol. II, pp. 49–224, Sg. 159a3
      Is airi ní táet comsuidigud fri rangabáil, húare as coibnesta do bréthir: ar is lour comsuidigud fri suidi, air bid comsuidigud etarscartha comsuidigud rangabálae.
      This is why composition does not occur with a participle, because it is akin to a verb: for composition with the latter is sufficient, for composition of a participle will be separated composition.
