[4] kjǫlsýja (f.) ‘garboard’: Lit. ‘keel-suture’ (cf. sýjur ‘clenchings’ in st. 5/3 above). The second element of this word is spelled (normalised) ‑sýgja in R and Tˣ (cf. ModIcel. kjalsýgja, kjalsíða, kjalsúla ‘garboard’, Sigfús Blöndal 1920-4, Tavle II C, no. 13). For ModEngl. garboard, the first range of planks laid upon a ship’s bottom, next to the keel’, see OED: garboard, n. Like kjǫlborð (see l. 3 above), kjǫlsýja is the term for the plank next to the keel (Falk 1912, 52). The word does not occur elsewhere in poetry.
