VERBS, AUXILIARY. Do, did, original use of
Do, Did: original use. In Early as in modern English, the present and past indefinite of the indicative were generally represented by inflected forms, as "He comes," "He came," without the aid of do or did. Do was then used only in the sense of "to cause," "to make," &c.; and in this sense was followed by an infinitive. “They have done her understonde.” GOWER.1 i.e. "they have caused her to understand." Similarly it is used like the French "faire" or "laisser" with the ellipsis of the person who is "caused" to do the action, thus-- “Do stripen me and put me in a sakke,And in the nexte river do me drenche.” CHAUCER, Marchante's Tale, 10,074. i.e. "cause (some one) to strip me--to drench me." In the same way "let" is repeatedly used in Early English: “He let make Sir Kay seneschal of England.” Morte d'Arthur. where a later author might have written "he did make." Gradually the force of the infinitive inflection en was weakened and forgotten; thus "do stripen" became "do strip," and do was used without any notion of causation.2 Sometimes do is reduplicated, as: “And thus he did do slen hem alle three.” CHAUCER, C. T. 7624. or used with "let," as in “He let the feste of his nativitee
Don crien.” CHAUCER, C. T. 10,360. The verb was sometimes used transitively with an objective noun, as: “He did thankingys.” WICKLIFFE, St. Matt. xv. 36. and so in Shakespeare in
“Do me some charity.

; Rich. III. v. 3. 210.“To do you salutation from his master.
”
and in the words "to don," i.e. "put on," and "dout," i.e. "put out." But as a rule do had become a mere auxiliary, so that we even find it an auxiliary to itself, as in“After the last enchantment you did here.
”
“Who does do you wrong?
