Lepton (1)
From Simon Online
Lepton grece macrum minutum tenue subtile parvum a quo infra scripta.
Apparatus:
tenue ABC e | tenule f {typesetting error}
Translation:
The Greek word lepton means lean, minute, thin, slender, small, and it will be used for explaining the names of some of the next entries. {e.g. Leptokarea, Leptolachanon, Leptomere, Leptopiresia}
Commentary:
Simon's form is the neuter λεπτόν /leptón/ of λεπτός /leptós/ which LSJ gloss as "peeled, husked; fine, small; thin, delicate".
