Phragmites

英['fræɡmaitis] 美['fræɡmaitis]

• 网络 芦苇属;芦根
• 英英释义
• 1. an invasive reed of the grass family with stems that can grow as tall as 20 ft. (6 m), found around the world in marshes and wetlands.
• 2. Noun: reeds of marshes and riversides in tropical or temperate regions

1. Phragmites ← 希腊语 phragmitēs "生长在篱笆间的(草)" ← phragmos "篱笆、围栏" ← phrassein (phrassō) "围起、圈住". 因芦苇密生成丛、秆高且直, 古人常刈割之编篱筑障而得名.
2. 词尾 -ites 为希腊语形容词词尾, 表"属于……的", 生物命名中常见; 种加词 australis "南方的" ← 拉丁语 auster "南风", 同根词有 austral (南方的), Australia (澳大利亚, "南方大陆"), Aurora australis (南极光).
3. 联想记忆: phragm- 形似 fragm- — fragment (碎片), fragile (易碎的), fracture (断裂) 均出自拉丁语 frangere "折断" (印欧词根 *breg-, 一说与希腊语 phrassein 同源——篱笆即把土地"折断、隔开"之物). 可记: 芦苇秆中空易折, 密集成"栅栏". (此组联想部分为记忆方便, 严格同源关系尚有争议)
4. 谐音记忆: Phragmites /fræɡˈmaɪtiːz/ 拆读 phrag-mi-tes ≈ "篱·密" — 芦苇密密丛生, 天然成篱; 重音在 -MY-teez, Ph- 读 /f/ 为希腊借词特征 (同 phone, photo, phase).
5. 英语日常称 common reed (普通芦苇); reed 又有"簧片"义, 因芦苇秆自古用作乐器簧片 — 潘神笛 即以芦苇制成, reed instruments 即"簧管乐器". 又, 本属旧用种加词 communis "普通的", 20世纪后半改定为 australis.
