'stern'(Modern English stern)
Usually derived from ON *steorn, cp. OIcel stjórn 'helm, steering'. The only evidence elsewhere in Gmc for an abstract formation on the root *steur- (as in the nouns (of various gender) represented by OE stēor 'steering, direction, guidance', OFris stiure, MLG stiure, stūre, OHG stiura, OIcel stýri, which originated as sb. adjectives, as in Go us-stiuriba 'dissolutely') with fem. -nō is OFris stiārne. An unattested OE *stēorn thus remains a possibility.
