"inalienable ownership," mid-15c., from Anglo-French morte mayn (mid-14c.), Old French mortemain, literally "dead hand," from Medieval Latin mortua manus; for first element see mortal (adj.); second is from PIE root *man- (2) "hand." Probably a metaphorical expression on the notion of dead hands as those that cannot alienate.
Entries linking to mortmain
late 14c., "deadly, destructive to life; causing or threatening death" (of illness, poisons, wounds, etc.); also, of persons or the body, "doomed to die, subject to death;" from Old French mortel "destined to die; deserving of death" and directly from Latin mortalis "subject to death, mortal, of a mortal, human," from mors (genitive mortis) "death."
This is reconstructed to be from PIE *mr-o- "to die," *mr-to- "dead," *mr-ti- "death," all from PIE root *mer- "to rub away, harm" (also "to die" and forming words referring to death and to beings subject to death). The most widespread Indo-European root for "to die," it forms the common word for it except in Greek and Germanic.
"Subject to death," hence "human, of or pertaining to humans" (early 15c.). Also from late 14c. as "implacable, to be satisfied only by death" (of hatreds, enemies, etc.).
