There are two elements of deafness (or d/Deafness) when it comes to the Deaf community.
Upper-case "D" Deaf: This term (Deaf) often refers to an individual who was born culturally Deaf and is an avid user of American Sign Language (ASL). This individual is proud to be considered Deaf and more than likely grew up in a local Deaf community with other Deaf individuals. Deaf individuals tend to see themselves as gaining Deaf Culture rather than losing their hearing and will often utilize the use of ASL as their main form of communication.
Lower-case "d" deaf: This term (deaf) often refers to a medical diagnosis rather than a cultural one. If a person who is born hearing loses this ability late in life (such as an elderly grandparent), they would be considered deaf rather than Deaf. These deaf individuals would likely utilize the use of hearing aids and have no real connection to the Deaf Community in most cases.
I hope this helps clear up your question!
