Etymology

It is inherited from Middle English declamen,[2][3][4] borrowed from Latin dēclāmō (“to practise public speaking; to bluster”),[5][2][6][3] and according to Etymonline, Barnhart and the Oxford Dictionary of English also French déclamer,[6][4][7] though the OED dates the French verb only to 1549.[5] The Latin verb is formed from dē- and clāmō (“to cry, shout”),[5][6][3] from Proto-Indo-European *kele- (“to shout”).[6] The prefix is taken as intensive by the American Heritage Dictionary and, with a "perhaps", by Etymonline,[3][6] and as "down, away" by Merriam-Webster Unabridged.[8] The word was spelled declame until the 17th century, when it was altered under the influence of claim.[4][6][8]

Earliest recorded meaning

To discuss aloud, to debate: c. 1374, in Chaucer's Troilus and Criseyde:[5] "And right as they declamed this matere".[2] Barnhart dates the same text about 1385.[4]

Semantic evolution

Chaucer's sense, to debate a matter, did not last.[5] From the 16th century the main sense was that of Latin, to speak on a set theme as an exercise in oratory.[5][6] From there it acquired a sense of display and excess: to declaim against something, to condemn it in impassioned speech, is recorded from 1611, in Jonson's Catiline,[5] and Johnson (1755) defines the verb as "to harangue; to speak to the passions; to rhetoricate; to speak set orations".[9] The sense of speaking with appeals to the emotions rather than to reason is dated 1735 by the OED and 1795 by Etymonline.[5][6] Thomas Hardy used declaim as a noun in 1922.[5]
