Etymology

It is inherited from Middle English elles, inherited from Old English elles (“otherwise, besides, different”),[2][3] the neuter genitive singular of a Germanic adjective meaning “other”, used as an adverb,[4][5][6] from Proto-Germanic *aljaz.[2][5] Barnhart traces it to Proto-Indo-European *alyos (“other”),[3] which Etymonline and Klein derive from a base *al- (“beyond”).[2][4] Its relatives include Latin alius (“other”), Ancient Greek ἄλλος (állos, “other”) and Old Irish aile,[3][4] and English alien, alias, alibi, alter, parallel and ulterior.[4]

Earliest recorded meaning

Other, otherwise, different: Old English elles, 971.[3] The compound elsewhere is older, from about 725 in Beowulf.[3]

Semantic evolution

Middle English elles became els in the 15th century and was spelled else in the late 16th and early 17th centuries.[3] Used after pronouns as a near-adjective meaning “other”, as in someone else, it is recorded from the 1660s.[2] The threatening or else, with the threat left unsaid, is found by 1814 in Walter Scott.[2] English formed many compounds that did not last, such as elsewhen (early 15th century), elsehow (1660s) and elsewards (1882), while elsewhere and elsewise survive.[2] The sense “in a different manner” was used from Old English times until about 1550.[7]

Usage notes

The American Heritage Dictionary considers else redundant after but, except and besides (no one else but Sam), and notes that the possessive is someone else's, not someone's else.[8]
