STEP-SON
,Noun.
[In the foregoing explication of step, I have followed Lye. The D. And G. Write stief, and the Swedes styf, before the name; a word which does not appear to be connected with any verb signifying to bereave, and the word is not without some difficulties. I have given the explanation which appears to be most probably correct. If the radical sense of step, a pace, is to part or open, the word coincides with Sax. Stepan, to deprive, and in the compounds above, step may imply removal or distance.]
