The lexical pair of Akkadian ṭarfāˀ-, but the data are insufficient for a reliable reconstruction. Possibly an Akkadian-Arabic borrowing, though without an Aramaic intermediary (Kogan 2012a:906, Kogan–Krebernik 2021a:392).
Is related to Proto-MSA *ṭVˁr- ‘clay’, but no further cognates elsewhere in Semitic could be detected. (Kogan 2015:573)
