pectio

Etymology 1
Apparently an abstract noun built on, although the formation is unusual: most comparable nouns are formed with the suffix (or equivalently, are built on the supine stem of the verb), which would yield *pexiō. If genuine, the word might be formed with the less common abstract noun suffix ; alternatively, as noted below, "pectione" could be a corruption of the original text.

Noun

 * 1)  the action of combing, a combing of the hair
 * 2) ** Some editors, following the "editio Rovilliana", emend ex pectione "from combing" to denso pectine "with a close-set comb".
