Pronunciation

  • Classical: [akˈkɫaː.moː][1]
  • Ecclesiastical: [akˈklaː.mo][1]

Forms

acclāmō (present infinitive acclāmāre, perfect active acclāmāvī, supine acclāmātum); first conjugation[1] It is also spelled adclāmō.[2][3]

Etymology

It is from Latin ad- (“to, at”) + clāmō (“to shout”).[2][4][5] De Vaan takes clāmō as a verb made from a lost noun for “shout”, from Proto-Italic *klām-o/ā- (“shout, shouting”) and Proto-Indo-European *klh₁-m(o)-, the root of calō1 (“to call”).[6]

Earliest recorded meaning

Its first uses are Cicero's, in a hostile sense: in the Verrines he calls a man the enemy of all who had shouted out against him, and in the Brutus he says he does not fear that his hearers will cry out at him.[2][3][4]

Semantic evolution

Lewis & Short note that in the time of the Republic it is mostly hostile, a crowd shouting its disapproval, as also in Velleius.[3][2] After the Augustan period it is chiefly to shout approval or applaud, as Tacitus has of the people and soldiers acclaiming Otho, and Livy of crowds hailing a man as saviour and liberator.[3][2] With direct speech it is simply to call out, as in Seneca and Suetonius.[2] Stelten glosses it “cry out at, shout, exclaim”.[7] Etymonline notes that it meant “to claim” in Medieval Latin, and that English acclaim, from the early 14th century, had that sense first;[5] “applaud” is recorded from the 1630s.[5]

  • early 14th century – English acclaim, first “to lay claim to”.[5]
