burial (n.) Look up burial at Dictionary.com
"act of burying," late 13c.; earlier "tomb" (c.1200), false singular from Old English byrgels "tomb," from byrgan "to bury" + suffix -els; a compound also found in Old Saxon burgisli, suggesting a Proto-Germanic *burgisli-, from PIE root *bhergh- (1) "to hide, protect" (see bury). The Germanic suffix *-isli- (also in Old English hydels "hiding place," fætels "bag") became obsolete and was felt as a plural of the Latin-derived suffix -al (2) forming nouns of action from verbs (survival, approval, etc.).
