juge

from Latin jūdĭcem, accusative of jūdex, derived from jūs ("law", "justice") and dīcĕre ("to say"), from the root deik- ("to show"). However, the French form juge cannot phonetically derive from jūdĭcem. One would expect juce (never attested). It can be assumed that the form juce, if it ever existed (?), could have been reworked, at a preliterary date, on juger (derived from jūdĭcare). Another possibility: juge could be derived from a form jūdĭcum, analogous to mĕdĭcum ("physician"), which had given miège in Old French.
