Forms
offirmō (present infinitive offirmāre, perfect active offirmāvī, supine offirmātum); first conjugation[1]
Etymology
It is from Latin ob- + firmō (“to make firm”).[2][3][1] That verb is formed from firmus (“firm”), which de Vaan traces to Proto-Italic *fermo- and Proto-Indo-European *dher-mo- (“holding”).[4]
Earliest recorded meaning
It is found from Plautus on,[4][3] meaning to make the mind hard and unyielding, or to make up one's mind: satin offirmātum quod mihi erat, id mē exōrat?, “am I being talked out of what I had firmly resolved?”[2]
Semantic evolution
In early Latin it is used of hardening the will or oneself (offirmā tē), and of making up one's mind to a course of action, in Plautus, Terence, Pacuvius and Accius.[2] Catullus has quīn tū animō offirmās, “why do you not steel your heart?”[2] In classical Latin it is mostly found in the participle offirmātus, “resolute, obstinate”.[5] Festus glosses offirmātō as “obstinate, persevering”.[3]
The physical sense, to make something fast, appears in Apuleius, of a pole used to bar the doors of a stable.[2][5]
