count
v.
mid-14c., from Old French conter "add up," but also "tell a story," from Latin computare (see compute). Related: Counted; counting. Modern French differentiates compter "to count" and conter "to tell," but they are cognates.
n.
title of nobility, c.1300, from Anglo-French counte (Old French conte), from Latin comitem (nominative comes) "companion, attendant," the Roman term for a provincial governor, from com- "with" (see com-) + stem of ire "to go" (see ion). The term was used in Anglo-French to render Old English eorl, but the word was never truly naturalized and mainly was used with reference to foreign titles.
