Mark the stress in each word you make:


Word One: Adjective that means “slow to learn; not intelligent”:

Word Two: Adjective + ity = Noun that means “the condition of being slow to learn and not intelligent”:


Word One: Adjective meaning “known by all or most people; open”:

Word Two: Adjective + ity = Noun meaning “information that brings something to the attention of many people”:
