Tilly

Applying free indirect style in a small way to a minor character, the narrative of Telemachus approaches the language of the old milkwoman when it says "She poured again a measureful and a tilly." Like the "baker's dozen" of English tradition, "tilly" is a Hiberno-English word for giving customers a little additional measure of the substance they are purchasing. It comes from the Irish tuilleadh, meaning "extra" or "added."
