Sinhala

Borrowed from Sinhalese සිංහල (siṁhala), itself borrowed from Sanskrit सिंहल (siṃhala, literally “lionlike”), from सिंह (siṃhá, “lion”) +‎ -ल (-la), recorded as the name of the island of Ceylon (Sri Lanka) from about the 10th to 12th century, but presumably older, as it is also the source of the name Ceylon in western geographic tradition.

The name is sometimes glossed as "abode of lions", referring to a supposed former abundance of lions on the island ( The Asiatic Journal 20 (1836), p. 30). Doublet of Ceylon and Elu.
