[2] ræsir (m.) ‘impeller’: A poetic word for ‘ruler’, and the name of one of the sons of Hálfdan gamli (see Introduction above). Falk (1889c, 258) argues that ræsir is a loanword from OE ræswa ‘leader’, but it is more likely to be an agent noun from the weak verb ræsa ‘set in motion’ (so AEW: ræsir; Björn Magnússon Ólsen 1923, 105-6). If so, it must be identical with the word ræsir which frequently occurs as a base-word in kennings for ‘man’ or ‘warrior’, where it is used in its literal sense (‘one who sets in motion, impeller’).
