  • To address as “thou”: implying (except when referring to the usage of the Friends) familiarity, wrath, scorn, contempt, etc.
  • To use thou, thee, thy, and thine in discourse, as do the Friends.
  • A personal pronoun of the second person, in the singular number, nominative case, the possessive case being thy or thine, and the objective thee: plural, ye or you, your, you. See thine and you.
  • In ordinary English use the place of thou has been taken by you, which is properly plural, and takes a plural verb. Thou is now little used except archaically, in poetry, provincially, in addressing the Deity, and by the Friends, who usually say not thou but thee, putting a verb in the third person singular with it: as, thee is or is thee?
  • Formerly it was used in general address, and often bore special significance, according to circumstances, as noting— equality, familiarity, or intimacy
  • superiority on the part of the speaker
  • contempt or scorn for the person addressed (see thou, v.).

  • pron: this pronoun is still much in use. Farmers in general ‘thou’ their servants; the inferior class (and the lower class of men in general) frequently their wives, and always their children; and the children as invariably ‘thou’ each other. Superiors in general ‘thou’ their inferiors; while inferiors ‘you’ their betters. Equals and intimates of the lower class generally ‘thou’ one another. These distinctions are sometimes the cause of aukwardness: to ‘you’ a man may be making too familiar with him; while to ‘thou’ him might affront him. PROVINCIALISMS OF EAST YORKSHIRE;BY MR. MARSHALL; 1788.
