logarithm: logarithm: [17] Greek lógos had a remarkably wide spread of meanings, ranging from ‘speech, saying’ to ‘reason, reckoning, calculation’, and ‘ratio’. The more ‘verbal’ end of its spectrum has given English the suffixes -logue and -logy (as in dialogue, tautology, etc), while the ‘reasoning’ component has contributed logic [14] (from the Greek derivative logiké), logistic [17] (from the Greek derivative logistikós ‘of calculation’), and logarithm, coined in the early 17th century by the English mathematician John Napier from Greek logós ‘ratio’ and arithmós ‘number’ (source of English arithmetic [13]).
