a homograph.

this is confusing. have you ever wonder why patient and patient spelled and pronounced the same? then how to explain the difference in meanings between these two words when they were put in a connected concept situation? like do a doctor always told their patient to be patient? or do someone need to embrace the experience of being a patient to learn how to be patient? or do a patient soul was once a suffering patient in the past, but now healed and activated their self-healing ability? i don't know. 

do you know?
