Conceptually Accurate Signed English (CASE)
Conceptually Accurate Signed English (CASE) — sometimes called Pidgin Signed English (PSE) — is a building block that has developed between people who use American Sign Language (ASL), and people who use Manually Coded English (MCE), using signs based on ASL and MCE. This helps them understand each other better.
In CASE, American Sign Language (ASL) and Manually Coded English (MCE) are blended together. CASE is flexible, and can be changed depending on the people using it.
Other building blocks can be used with CASE. Often, finger spelling is used in combination with CASE. Finger spelling is used to spell out words that don’t have a sign — such as names of people and places.
