The meaning of particular words may, of course, be ascertained by reference to the meaning of words with which they are associated. This, noscitur a sociis, was accepted as a process of interpretation as early as Bacon: see Bacon's Abridgement, Vol VII, p452, par 2; Jonmenjoy Coondoo v Watson; see Hay v Earl of Coventry. The process of reading down general words by reference to accompanying particular words, said to be a variation of noscitur a sociis, also has a long history, but one which has varied. In an early form, for example, it limited general words to the extent that a particularization of inferior persons or things was seen as indicating that the general words did not extend to superior persons or things: see, eg the Archbishop of Canterbury's case. The present ejusdem generis process, whereby general words are restricted by the genus of the foregoing particular words, emerged, it has been suggested, only at a later stage: see the article by Glanville Williams in (1943) 7 The Conveyancer and Property Lawyer (New Series), p119, at p120 et seq. Since the end of the eighteenth century it has, Dr Glanville Williams suggests, 'caused a great deal of litigation and seems frequently to have thwarted the intentions of the draftsmen of statutes, deeds, wills, contracts and memorandums of association.'
