Deaf is to post as blind is to read.

Sordo (talking about a man)

Sorda (talking about a woman)

El es sordo - He is deaf.

Ella es sorda - She is deaf.

Deaf people who use sign language typically process language in their left cerebral hemisphere.

in most cases children of deaf parents, whether they themselves are deaf or not, are more academiclly successful. This is because they develop true language much earlier in their lives and learn faster, because words or the "concrete" part of language is harder for children to comprehend while the conceptual aka "abstract" is less so. As well as they do not need to delevop the speech centers of their brians in order to commuincate something which develops later on in their lives.

If a deaf person has a tongue tie problem, there is a surgery that can correct the tie of the tongue. This surgery separates the tongue from the attachment at the base.
