What's the difference between i.e. and e.g.?
"footstalk of a leaf," 1753, from French pétiole (18c.), from Late Latin petiolus, misspelling of peciolus "stalk, stem," literally "little foot," diminutive of pediculus "foot stalk," itself a diminutive of pes (genitive pedis) "foot" (see foot (n.)). Given its modern sense by Linnaeus.
petiole pet·i·ole (pět'ē-ōl')
A stem or pedicle.
