Several nouns appear as plural in Shakespearean English which are singular in modern English, and there are other kinds of number difference, as illustrated in the selection below. Plurality may be shown both by the form of the word (as in modern boy > boys) or by its agreement with the verb or determiner (as in this sheep is > these sheep are).
The Shakespearean situation is complicated by the existence of forms which might reflect a personal or regional dialect, as well as by usages which may be the result of printing errors.
  Examples include Shylock’s use of beefs and muttons and the various plurals used by speakers with a Welsh background, such as disparagements ( WELSH). Examples of the reverse process (singular > plural) can also be found, as in ‘their business still lies out o’door’ (CE II.i.11) alongside ‘out of doors’ (Cor I.iii.72), and ‘conquer other by the dint of sword’ (E3 V.i.52), where modern usage whould use others.
