Pronunciation & Spelling
Most of these share the unstressed ending /ətɪvnəs/ with representativeness (e.g., talkativeness, positiveness, sensitiveness, imaginativeness, argumentativeness); they are not full rhymes because the main stress falls earlier. Creativeness is a spelling and sound lookalike: its stressed part is /eɪtɪ/, so it does not match the /ətɪ/ of the others. Also note that representativeness is spelled with -ativeness, not -itiveness.
