Usage note
The possessive forms of somebody else, everybody else, etc., are somebody else's, everybody else's, the forms somebody's else, everybody's else being considered nonstandard in present-day English. One exception is the possessive for who else, which is occasionally formed as whose else when a noun does not immediately follow: Is this book yours? Whose else could it be? No, it's somebody else's.

else

adj.

Old English elles "other, otherwise, different," from Proto-Germanic *aljaz (cf. Gothic aljis "other," Old High German eli-lenti, Old English el-lende, both meaning "in a foreign land;" see also Alsace), an adverbial genitive of the neuter of PIE root *al- "beyond" (cf. Greek allos "other," Latin alius; see alias). Synonym of other, the nuances of usage are often arbitrary.

" something else, anything else;" elsewhen (adv.), early 15c., "at another time; elsewhence (c.1600); elsewho (1540s). Among the survivors are elsewhere, elsewise.
