As a quality of style, “Purity … relates to three things, viz. the form of words [etymology], the construction of words in continuous discourse [syntax], and the meaning of words and phrases [lexicography].” (A. Phelps, Eng. Style, p. 9.) “Propriety … relates to the signification of language as fixed by usage.” (A. Phelps, Eng. Style, p. 79.) “The offences against the usage of the English language are … improprieties, words or phrases used in a sense not English.” (A. S. Hill, Rhet., p. 19.) “An author's diction is pure when he uses such words only as belong to the idiom of the language, in opposition to words that are foreign, obsolete, newly coined, or without proper authority. … A violation of purity is called a barbarism. … But another question arises. … Is the word used correctly in the sentence in which it occurs? … A writer who fails in this respect offends against propriety.” (J. S. Hart, Comp. and Rhet., pp. 68, 74.) “Precision includes all that is essential to the expression of no more, no less, and no other than the meaning which the writer purposes to express.”n.
