undulate
undulate: [17] Undulate goes back ultimately to Latin unda ‘wave’, source also of English inundate [17], redundant, and surround. This in turn was descended from the Indo-European base *ud-, which also produced Greek húdōr ‘water’ (source of the English prefix hydro-), and variants of which lie behind English vodka, water, and wet.
=> abound, inundate, redundant, sound, surround
undulate (v.)
"to move in waves," 1660s, back-formation from undulation. Related: undulated, undulating.

中文解释

1. und- + -ul- (diminutive affix) + -ate.2. => wavy.3. same PIE base words: vodka, water, wet, otter.
