バイデン大統領のお別れの演説に会場が拍手喝采に見舞われました。
Speaking to a packed arena in Chicago on the first night of the Democratic National Convention, Mr Biden offered a full-throated defence of his presidency – touching on many of the themes that he campaigned on in 2020 and again this year before abandoning his re-election bid in mid-July, a few weeks after a catastrophic debate performance.
"Like many of you, I gave my heart and soul to this nation,” he said, towards the end of a nearly hour-long address punctuated by raucous shouts of "Thank you, Joe".
Joe Biden eyes legacy in emotional farewell at Democratic convention
今回取り上げるのは raucous /rˈɔːkəs/です。
Cambridge Dictionary では"loud and unpleasant"と定義されています。
LDOCE では、"sounding unpleasantly loud", "impolite, noisy, and violent"とあります。
語源をonline etymology dictionaryで調べると、"hoarse, harsh or croaking in sound," 1769, with -ous + Latin raucus "hoarse" (also source of French rauque, Spanish ronco, Italian rauco), from or related to ravus "hoarse," from Proto-Italic *rawo-, from PIE echoic base *reu- "to roar, make hoarse cries" (source also of Sanskrit rayati "barks," ravati "roars;" Greek oryesthai "to howl, roar;" Latin racco "a roar;" Old Church Slavonic rjevo "I roar;" Lithuanian rėkti "roar;" Old English rarian "to wail, bellow"). Middle English had rauc in the same sense, from Old French rauque and directly from Latin raucus."とあります。
以上のことからraucousは騒々しいという意味だと分かります。(en)
