Subtractive morphemes are illustrated by the masculine forms of certain French adjectives. In the series "plat" /pla/ : "platte" /plat/ "flat", "laid" /lɛ/ : "laide" /lɛd/ "ugly",”long” /lõ/ “long”, “soûl” /su/ : “soûle” /sul/ “drunk”, the subtractive element (the final consonant of the feminine forms) has different phonological shapes- /t, d, g, l/; but at least is always final.
