[7] ginhafri (m.) ‘false-oats’: A hap. leg. This heiti most likely designates a kind of oats (hafri). The word might be related to Orkney ginn ‘a kind of wild oats’ (also used as the first element in compounds, e.g ginnowy ‘poor oats’; see Marwick 1929, 54 and Grøn 1927, 38-9) and ON ginn m. ‘deceit’. Finnur Jónsson (LP: ginhafri) derives the first part of the word from gin n. ‘mouth’ (of beasts) and hence interprets this heiti as ‘gaping oats’.
