noun, masculine/mɛʁ.lɔ̃/plural: merlons
merlon
From Italian merlone (“merlon”), from merlo (“merlon”) + -one (suffix forming augmentatives). Merlo is derived from Late Latin merulus, merlus, possibly from Latin merula (“blackbird”) (as merlons resemble a row of birds perched on a wall), from Proto-Indo-European *h₂ems- (“black; blackbird”).
