Pronunciation

  • Classical: [deː.faˈtiː.ɡoː][1]
  • Ecclesiastical: [de.faˈtiː.ɡo][1]

Forms

dēfatīgō (present infinitive dēfatīgāre, perfect active dēfatīgāvī, supine dēfatīgātum); first conjugation[1] It is also spelled dēfetīgō, the usual form in manuscripts.[2][3][4]

Etymology

It is from Latin dē- + fatīgō (“to tire”).[2][1][4] De Vaan bases fatīgō and its family on a noun Proto-Italic *fati- (“exhaustion”), preserved in affatim;[5] Dunkel explains the verb as a compound of that noun with the root of agō.[5]

Earliest recorded meaning

De Vaan dates it from Plautus.[5] The OLD's first quotations are in Terence: in the Phormio a young woman may wear a man out, and in the Andria a man says he has been deceived but not worn down.[2]

Semantic evolution

It is to tire out or exhaust in body or mind: Caesar writes of fresh troops relieving tired ones and wearing out his men.[3][2] Columella uses it of soil exhausted by the yield of the previous year, Seneca of breaking the force of a blow.[2] In the passive it is to lose heart, and with a gerundive to grow weary of doing something: Cicero urges his hearer not to tire of saving good men.[2] Church Latin glosses it to exhaust, wear out, tire.[6]
