agolum

Uncertain. Probably related to agō (“to do”). De Vaan suggests that the term might be an Old Latin spelling for *agulum, which would reflect older *age-los. The linguist Benedicte Nielsen suggests that the term could reflect earlier *h₂aǵ-tlom, itself from *h₂eǵ- +‎ *-tlom, which she suggests may also be the source for Sanskrit aṣṭrā (“goad”). However, this theory requires an initial long-ā vowel. The length of the vowel is not definitively affirmed by the text, though Nielsen suggests that the term coāgulum attests to the existence of initial long-vowels in words derived from the same root.
