Etymologies

from The American Heritage® Dictionary of the English Language, 4th Edition

[Latin aquaeductus : aquae, genitive of aqua, water; see aqua + ductus, a leading; see duct.]

from Wiktionary, Creative Commons Attribution/Share-Alike License

Adapted from the Latin aquaeductus ("conveyance of water"), from aqua ("water") + dūcō ("I lead”, “I bring"); compare the French aquéduc.

Examples

    Glossary

  • Blockage at the aqueduct is assumed when the lateral and third ventricles are enlarged proximal to the obstruction, and the fourth ventricle is relatively small.

  • The aqueduct is dry now, having long ago been replaced with a more modern water system with higher capacity.

  • A quick unscientific survey: Do you say /ækwədʌkt/ or /ɑkwədʌkt/? In other words, does the first vowel rhyme with "yeah" or with "blah"?

    I just realized that I use /æ/ for "aqueduct" but /ɑ/ for "aqua", which seems terribly inconsistent of me.

  • "Ah" for me.
