'annuloida' originates from 'Swedish', specifically the word 'annullera', ultimately from French 'annuler' and Latin 'annullāre' (or 'annulare'), where elements meant 'to make void' or 'to reduce to nothing'.

'annuloida' changed from Swedish word 'annullera', which came from French 'annuler', itself from Latin 'annullāre' (related to 'ad-' + 'nullus'/'null-'), and eventually entered Finnish as the verb 'annuloida'.

Initially, the root terms carried the sense 'to make into nothing' or 'to reduce to zero'; over time this evolved into the legal/administrative sense 'to annul, cancel, or declare invalid', which is the current meaning.
