Tar-Telemmaitë was the 15th ruler of Númenor (LotR/1035), so called because of his love of silver (UT/221). Christopher Tolkien translated his name as “Silver-handed” (UTI/Tar-Telemmaitë). His name seems to be a compound of an assimilated form of telpë (telep-) “silver” and the adjective element maitë “-handed”.
