Hi JoLene,

thanks so much for clarifying that. Who'd a thunk?

Prelingual Deafness: a Definition

Prelingual Deafness, for the purposes of this discussion, means

deafness in persons whose onset was before they learned the language

of their environment. People generally learn their first language well

before age five, i.e., persons who were either deaf at birth

(congenital deafness) or who became deaf from disease or accident

(adventitious deafness) prior to developing the basics of the grammar

of the language of their environment.

Prelingual Hard-of-Hearing: a Definition

Prelingual Hard-of-Hearing, for the purposes of this discussion, means

partial deafness in persons whose onset was before they learned the

language of their environment. People generally learn their first

language well before age five, i.e., persons who were either

hard-of-hearing at birth (congenital hard-of-hearing) or who became

hard-of-hearing from disease or accident prior to developing the

basics of the grammar of the language of their environment.
