OE. stéop- (earlier stéup-, Northumb. stéap-), corresponding to OFris. stiap-, stiep- (NFris. stjap-, sjap-, stîp-, WFris. stiep-), MLG. (irreg.) stêf- (mod. LG. staif-), (M)Du. (irreg.) stief-, OHG. stiuf- (MHG., mod.G. stief-), ON. stjúp-, (MSw. stiup-, stiuf-; mod.Sw. stiuf-, styf-; Da. stif-, stiv-, now superseded by sted-):OTeut. *steupo-; a Com. Teut. combining element (not recorded in Gothic), prefixed to terms of relationship (as son, father, brother) to form designations for the degrees of affinity resulting from the remarriage of a widowed parent, The primitive sense of the word is indicated by the use of OE. stéopbearn, -cild (STEPBAIRN, STEPCHILD) for orphan, and by the cognates, OE. ástíeped bereaved, OHG. stiufen (also ar-, bistiufen) to bereave. Etymologically, stepfather (stepmother) might be rendered one who becomes a father (mother) to an orphan, and stepson (stepdaughter) an orphan who becomes a son (a daughter) by the marriage of the surviving parent. It is uncertain which of these two applications of the prefix is the original one; all branches of Teut. (exc. Gothic) have both, and also the extended use in stepbrother, stepsister. ON. had shortened forms, stjúpa stepmother, stjúp-r (mod.Icel. stjúpi) stepson. In Du. and LG., and in later Scandinavian, the p of OTeut. *steupo- is anomalously represented by f instead of p. This is prob. not due to HG. influence, but to assimilation to the following f in the compound stepfather (cf. the early ME. form steffadyr). A solitary OE. example of this anomaly occurs in the form stéfdohtor (quot. 912 s.v. STEPDAUGHTER). Occasional forms of the prefix in ME. are stip- (styp-), sti-, ste-, stappe-.
In 1755 Johnson, says that stepmother is the only one of the compounds of step- that has survived in general use. At the present day stepfather is hardly less frequently used, and stepson, -daughter, -child, -brother, -sister are by no means rare, while stepdame occurs in somewhat archaistic language (chiefly fig.). In the 16th and 17th c. a few writers employed the prefix in nonce-formations which would now seem un-English, as step-devil, a term of abhorrence for a stepmother; step-duchess, the stepmother of a dukes children; step-lord, one who has the position of a lord without the true lords affection for his subjects; step-Tully, one who assumes the function of a Cicero. New formations with the prefix, denoting actual relations of affinity, do not appear earlier than the 19th c.; in the latter part of the century they became somewhat common, chiefly as more or less jocular nonce-words, though one or two of them, as step-nephew, niece, have obtained some currency in serious use. The older compounds of step- are in this Dictionary treated as main words; the following examples illustrate the extended applications of the prefix from the 16th c. onwards.
