Etymology tree
Forms
flātus m (genitive flātūs); fourth declension[1]
Etymology
It is from Latin flō (“to blow”) + -tus, a verbal noun of the fourth declension.[2][3][1] De Vaan tentatively traces flō to Proto-Indo-European *bʰleh₁- (“to blow”), perhaps related to fleō (“to weep”).[4]
Earliest recorded meaning
Köbler's first source is Varro;[5] Cicero writes in a letter that the south wind blowing hard against him carried him back to Regium.[2]
Semantic evolution
It is the blowing of the wind, a blast or breeze, as in Catullus' villa exposed to the blasts of the south wind.[2] Of people it is breathing or a breath, especially a laboured one, a breath blown to kindle a fire, and in Horace the sound of a pipe.[2][6] Vitruvius uses it of a blast from bellows and of vapours rising from the ground, and Suetonius of wind from the bowels: Claudius planned an edict allowing it at dinner.[2] Figuratively it is pride or vainglory, as in Seneca.[2]
Church Latin glosses it “breath, blowing, blast”,[7] and in medieval texts it is the breath of life, the soul.[8]
