eructation (n.)

"belching," 1530s, from Latin eructationem (nominative eructatio) "a belching forth," noun of action from past participle stem of eructare "to belch forth, vomit," from assimilated form of ex- "out" (see ex-) + ructare "to belch," from PIE *reug- "to belch" (cognates: Lithuanian rugiu "to belch," Greek eryge, Armenian orcam), which is probably imitative.
