Heitask

As defined by the Cleasby & Vigfusson Old Norse to English dictionary:

heitask

að, dep.; [in mod. usage this word is often used as a strong verb, as if it belonged to the great verb heita above; but wrongly, as they are widely different, the former referring to Goth. haitjan, the latter to Goth. wôtjan, answering to Icel. hóta, hœta, q. v., Old Engl. to wite]:—to hoot, threaten, abuse one; heitask við e-n, with infin. or absol., hann gerir reiðan mjök ok heitask við Odd, Korm. 142; aldrei hallmælti hann úvinum sínum ok aldri heitaðisk hann við þá, and he never spoke evil of or abused his enemies, Nj. 211; hann settisk í bú hans en heitaðisk við bónda, Fs. 157; hverr ert þú svá djarfr, at þú þorir at heitask við höfðingja várn? Fms. i. 75: with infin., heituðusk Danir mjök at fara með her í Noreg, 160; h. e-s, viii. 167; þeir heitaðusk at verja hann, vii. 290; Knútr heitaðisk jafnan at herja til Englands, Ísl. ii. 241; en hjónin heituðusk við í öðru lagi at hlaupa á brott, Bjarn. 27; hann heitask at brjóta þau, O. H. l. 23; h. til e-s, muntú ná goðorði þínu þó at þú heitisk eigi til, Þorst. Síðu H. 173: absol., segir at konungi mundi þat eigi duga at heitask eðr herja á innan-lands fólk, Hkr. i. 144. In mod. language heitast is chiefly used of those who shortly before death curse a man, and after death haunt him, see Ísl. Þjóðs. i. 222.
