þekkja ‘dear’: As a ja-/jō-stem adj. þekkr has the normalised f. acc. sg. form þekkja, which is the form found in Flat, but 61, 54 and Bb have þekka, an alternative declensional form which occurs by analogy with a-stem adjectives (ANG §431). The word is taken here as an adj. agreeing with hugrekki ‘courage’ (so LP: þekkr). The form þekkja could alternatively be an inf. verb, hence lét þekkja sér hugrekki ‘allowed himself to be pleased with courage’ though the m. v. þekkjask would be more usual in this sense.
