water
English 'water' and Spanish 'agua' look like cousins but are not: they descend from two different Proto-Indo-European words, a fracture that opened before the Romans named the aqueduct or the Germanic tribes named the rain. Esperanto bridges this gap artificially, borrowing 'akvo' from Latin and so agreeing with Spanish where it might just as easily have agreed with English. Chinese 水 takes an entirely different path — not a word selected to name water but a picture of a river drawn from life, the central channel flanked by flowing tributaries, before writing and naming had fully parted ways. What strikes the comparatist is that Europe spent millennia holding two separate roots for the same liquid and never quite noticed, while Chinese encoded the concept once, in a single stroke, as motion.
Across languages
'Agua' is grammatically feminine but takes a masculine singular article when the stressed syllable opens the word: 'el agua fría' (not 'la agua'), though 'las aguas' in the plural.
An oracle-bone pictograph of a river seen from above: the central stroke is the main current, and the flanking curves are its tributaries in motion. Water rendered not as a substance but as a flow — the river, not the drop.
水 serves as Kangxi radical 85 and appears in reduced form as 氵 (the 'three-dot water' radical) in hundreds of characters relating to liquid, moisture, rivers, and washing.

Esperanto builds freely on this root: akvaro (aquarium), akvofalo (waterfall), akvumi (to water plants). The morpheme 'akv-' is borrowed; the '-o' is the universal Esperanto noun ending.
