"extemporaneously"是副詞，詞根源于拉丁語"ex tempore"，字面含義為"出于當下"，指未經預先準備或即興完成的行為。該詞在專業領域中有三個核心應用方向：
公共演講領域
指演講者不依賴講稿，根據現場情況臨時組織語言的表現形式。美國國家演講協會（National Speech Association）将其定義為"通過提綱或關鍵詞提示，實時構建邏輯連貫的演講内容"（來源：speechassociation.org/speech-glossary）。
表演藝術領域
在戲劇和音樂場景中，特指演員或樂手脫離劇本/樂譜進行的創造性發揮。伯克利音樂學院表演研究指出，這種即興創作需建立在紮實的專業訓練基礎上（來源：berklee.edu/improvisation-techniques）。
學術寫作規範
芝加哥格式手冊（Chicago Manual of Style）特别說明，學術場景使用該詞時多指"基于已知材料的臨時性口頭闡述"，區别于完全即興的臨場發揮（來源：chicagomanualofstyle.org/oral-presentation）。
詞義演變方面，牛津英語詞典（OED）曆史語料庫顯示，19世紀後該詞逐漸從單純的"臨時性"含義，發展為包含"基于專業儲備的創造性輸出"這層專業語義（來源：oed.com/historical-lexicography）。
單詞extemporaneously 是副詞，主要含義為“即興地、無準備地”，強調在未經提前計劃或排練的情況下完成某事，尤其在演講、表演等場景中使用。以下是詳細解析：
He spoke extemporaneously at the conference.（他在會議上即興發言。）
