Note to Þul Skjaldar 1III
[1] þrunginsalr (m.) ‘crowded hall’: A cpd not attested elsewhere, where the first element is derived from þrunginn, p. p. of the strong verb þryngva ‘crowd, fill up, force, oppress’, and the second element is salr m. ‘hall’. According to Falk (1914b, 126 n. 5), the heiti þrunginsalr refers to a skjaldborg ‘shield-wall’, a traditional battle formation, and hence should be interpreted as a half-kenning that requires a determinant, namely, one of Óðinn’s names. Alternatively, and perhaps more likely, this heiti could be a metonomic reference to the custom of warriors leaving their shields against the wall of a hall when on a friendly visit.
