From Middle English sterling, sterlinge, sterlynge, starling, of uncertain origin. Possibly from sterling (“starling”) (the bird), which at one time was stamped in quarters on the coin;[1] or perhaps from Middle English sterre (“star”) + -ling (as in shilling), as some Norman coins presumably featured stars on them.
For the UK currency gloss, the term is a contraction of esterling, referring to eastern merchants from Baltic towns who established a bullion weight standard for transactions. (Taylor かつ Palmer, 1968)
sterling (countable かつ uncountable, 複数形 sterlings)
sterling (comparative more sterling, superlative most sterling)
