"act or custom of burning of the dead," 1620s, from Latin cremationem (nominative crematio), noun of action from past-participle stem of cremare "to burn, consume by fire" (also used of the dead), from PIE *krem-, extended form of root *ker- (3) "heat, fire."
The adoption of cremation would relieve us of a muck of threadbare burial-witticisms; but, on the other hand, it would resurrect a lot of mildewed old cremation-jokes that have had a rest for two thousand years. ["Mark Twain," "Life on the Mississippi," 1883]
Old English heorð "hearth, fireplace, part of a floor on which a fire is made," also in transferred use "house, home, fireside," from Proto-Germanic *hertha- "burning place" (source also of Old Saxon and Old Frisian herth, Middle Dutch hert, Dutch haard, German Herd "floor, ground, fireplace"), from PIE *kerta-, from root *ker- (3) "heat, fire."

1610s, "act of growing by organic enlargement;" 1650s as "that which is formed by continued growth from without," from Latin accretionem (nominative accretio) "an increasing, a growing larger" (as of the waxing moon), noun of action from past-participle stem of accrescere "grow progressively, increase, become greater," from ad "to" (see ad-) + crescere "grow" (from PIE root *ker- (2) "to grow"). It goes with the verb accrue. Related: Accretional; accretionary.
Apparently an English verb from a French noun because there is no English noun to go with it until much later (the earliest seems to be now-obsolete accrue, 1570s), unless the record is defective. From late 15c. as "happen or result as a natural growth;" from 1881 as "gain by increment, accumulate." Alternative verb accrete "grow by adhesion" (1784) is rare, as is accresce (1630s), from Latin accrescere.
1832, "grass yielding edible grain and cultivated for food," originally an adjective (1818) "having to do with edible grain," from French céréale (16c., "of Ceres;" 18c. in grain sense), from Latin Cerealis "of grain," originally "of Ceres," from Ceres, Italic goddess of agriculture, from PIE *ker-es-, from root *ker- (2) "to grow." The application to breakfast food cereal made from grain is American English, 1899.
