merciful

Etymology

It is formed from English mercy + -ful,^[2][3][4][5] in Middle English mercīful, also mercivol and mersiful.^[6] Etymonline notes that the earlier word was merciable, from about 1200.^[3] The noun mercy is from Anglo-Norman merci, also merci, from Latin mercēs (“wages, fee, reward”), cognate with merx (“goods, merchandise”), the source of market.^[2][3]

Earliest recorded meaning

Having or showing mercy: 1340, in the Ayenbite, Yblissed byeþ þe merciuolle, uor hi ssolle uynde merci, where it is already a noun for merciful people.^[2][6] Etymonline has the mid-14th century, and Dictionary.com 1250–1300.^[3][7]

Semantic evolution

The Middle English Dictionary's first sense is forgiving towards sinners and enemies, as in the Wycliffite Bible, where it renders Latin misericors and propitius.^[6] Middle English widened it to compassionate, to kind and helpful, even of a beneficial medicine, and to generous.^[6] Johnson (1755) still gave "compassionate; tender; kind; unwilling to punish".^[5] A new sense appeared in the 19th century: bringing relief from misery, recorded from 1836, and in a weakened form from anything awkward, so that it comes close to "fortunate, welcome".^[2][8] Scots and English dialects went further: in Shetland merciful weather was seasonable, in southern Scotland the word meant lucky, in Kent it was an intensifier, and in Worcestershire an adverb, "very".^[9]
