noun, masculine/pa.sʁo/plural: passereaux
sparrow; passerine
“Déchiré par les serres d’un Aigle, un Lièvre poussait de longs gémissements. Un Passereau l’insultait” — A Sparrow upbraided a Hare that had been pounced upon by an Eagle, and was sending forth piercing cries.
Inherited from Old French passerel, from Latin passer + French suffix -eau. Ultimately from Proto-Indo-European *p(e)t-tro- (“who flies, bird”), from *peth₂- (“to fly”).
