I am writing a paper on inflectional morphemes in English. The literature reviewed so far listed six inflectional morphemes in English which exclude 'y'. Two criteria were used in selecting the inflectional morphemes: a. It should be a suffix b. when added to a free morpheme changes the word class and in the case of verbs it sometimes changes the tense. Looking at this paradigm of words. Shall we not describe the 'y' added to them as the 'seventh' inflectional morpheme in English.( lad =lady; air =airy; man = many; hand = handy; arm = army; fuss = fussy; glutton = gluttony; fuzz = fuzzy; luck = lucky etc. Some many have read something on this already. I want experts' view on this.
