The word "lexicalized" means "to have become like a word."
In sign language lexicalized means to be produced like a "sign."
Two common examples of this include:
1: A Fingerspelled word that has mutated to look and be produced
more like a sign rather than typical fingerspelling.
2: Former classifiers that have been produced so frequently
and used so widely that they have frozen into commonly recognized
Student: What else is lexicalized? Is there such a thing as
a lexicalized facial expression?
Dr. Bill: Great question! A case could probably be made
certain facial expressions are commonly recognized as consistently
carrying a specific meaning. The "I'm so shocked!" facial
expression is a possible example.
Mouth morphemes could be considered "lexicalized mouth movements."
The mouth morpheme "PAH!" is commonly accepted to mean "Finally, at
last, success!" Interestingly, many people recognize that
mouth movement independent of its typically accompanying sign
"SUCCESS-(finally)"? If people do recognize the mouthing of
PAH! independent of the hand movements then it seems fair to label "PAH!"
as a lexicalized facial expression.
It is also very common to see some Deaf mouth a certain swear word
while using a head-thrust.
It functions very much like a "sign" even though it doesn't rely on
The combination is widely recognized and
understood. Thus it seems reasonable to consider it a
lexicalized "something" but I won't be so bold as to suggest a
Nodding "yes" and/or shaking your head "no" could be considered
"lexicalized head movements."
