West African nation, literally "lion mountains," from Spanish sierra "mountain range" (see sierra) + leon "lion" (see lion). Attested from mid-15c. in Portuguese explorers' accounts, and a very early explanation of the name derives it from the "roaring" of thunder in the mountains. Related: Sierra Leonean.
