COMMENT: Despite superficial dissimilarity, the EC-WC comparison is phonetically quite regular. The PWC form has regularly lost resonants, but the medial *-j- (reconstructed on basis of the PN reflex *sṭ) has left a trace in the palatalisation of the PWC affricate. In most languages the root means 'autumn', but sometimes also 'winter' or 'spring'; it probably denoted the rainy season in general.
