Final answer:
Lexicalized fingerspelled words are ASL words that began as English word spellings but are now unique signs with distinct movements and shapes in ASL.
Step-by-step explanation:
Lexicalized fingerspelled words, according to Battison, refer to words in American Sign Language (ASL) that originally came from English words spelled out letter by letter but have since developed into unique, abbreviated signs in ASL. These lexicalized fingerspelled words often exhibit changes such as movement, palm orientation, and handshape that differentiate them from their fully fingerspelled counterparts. Examples of lexicalized fingerspelled words are not provided in the references given, but such words could include #1, #2, and #3, where the numbers represent specific fingerspelled words that have become lexicalized in ASL.
