sewer: [15] Etymologically, sewer denotes the ‘removal of water’. The word comes via Anglo- Norman sever from Vulgar Latin *exaquāria, a derivative of *exaquāre ‘remove water, drain’. This was a compound verb formed from Latin ex- ‘out’ and aqua ‘water’. The derivatives sewage [19] and sewerage [19] are both native English formations. => aquatic
sewer (n.1)
c. 1400, "conduit," from Anglo-French sewere, Old North French sewiere "sluice from a pond" (13c.), literally "something that makes water flow," from shortened form of Gallo-Roman *exaquaria (source of Middle French esseveur), from Latin ex- "out" (see ex-) + aquaria, fem. of aquarius "pertaining to water," from aqua "water" (see aqua-).
Specifically of underground channels for wastewater from c. 1600; figurative use of this is from 1640s.

中文解释
1. 谐音“疏哦、疏尔、馊哦”-----疏导污水哦、疏导馊水哦。2. ewer => sewer.3. ex- => es- => s- + ewer (大口水壶, 其本义就是“水”) => sewer "removal of water, something that makes water out".4. 由此可以看出，ewer 与 sewer 是同源词，他们都源于拉丁语 aqua "water" (aquaria, fem. of aquarius "pertaining to water")，只是在进入法语后，在漫长的演化过程，被改得面目全非，最终就变成了今天的样子，而英语就是从法语中引入的，如果英语直接从拉丁语中引入的话，就应该是这样的：ewer => aquary, sewer => exaquary.
