“…Smell vocabularies have previously been considered a characteristic of small languages with few speakers [51] (of the existing 6500 languages, the median number of speakers is less than 1000) and particularly likely to appear in hunter-gatherer languages [59,60]. Numerous hunter-gatherer languages have indeed been reported with smell vocabularies [8,12,41,43,[59][60][61][62], but sizeable smell lexicons have also been reported in various pastoral and horticultural communities [37,42,61,[63][64][65][66][67][68][69][70][71][72] as well as in major languages of industrialized societies with millions of speakers [51,73]. It could be that smell lexicons are more likely to appear in small languages or hunter-gatherer contexts, but it is premature to conclude so.…”
