<注釋>Fans watching contact sports such as boxing, hockey, or football in modern arenas might be struck by the connection between the wordarena and the notion of gladiatorial combat. This word is from Latinharôna (also spelled arôna ), .sand.. Harôna then came to mean the part of a Roman amphitheater that was covered with sand to absorb the blood spilled by the combatants.Arena is first recorded in English during the 7th century, denoting this area of a Roman amphitheater.
在現(xiàn)代劇場(chǎng)中觀看接觸運(yùn)動(dòng)如拳擊、曲棍球或足球的愛好者們可能會(huì)發(fā)現(xiàn)單詞arena 與競(jìng)技搏斗概念的關(guān)系。 這個(gè)單詞來源于拉丁語(yǔ)harena （也拼作 arena) ，.沙地.。 Harena 后來便意指著羅馬圓形劇場(chǎng)的一部分， 它由沙覆蓋以吸收競(jìng)技斗士濺出的鮮血。Arena 在7世紀(jì)首次記入英語(yǔ)，意指羅馬圓形競(jìng)技場(chǎng)的這部分
