From Proto-Italic *wekslom (note the Latin term's diminutive form vēxillum (as in pālus > pāxillus), which lends credence to this reconstruction), with two competing theories: * From Proto-Indo-European *wegslom, from *weg- (“to weave, bind”). Cognate with English wick, Welsh gweu (“to weave”). * Others refer it to *weǵʰ- (“to ride”), thus "that which propels"; in this case, cognate with Proto-Slavic *veslo (“oar”). This is semantically less attractive than the above theory.
