save in terms of language

If one will scoff at the study of language, how, save in terms of language, will one scoff? - Mario Pei

“save in terms of language” - Which sense of “save” has been used above? Is it functioning as a preposition here? Please try to suggest the ‘sense’ out of M-W. Thanks.

M-W: merriam-webster.com/dictionary/save

Save= except

Did “save in terms of language” scoff that your language ability is limited ? Right? When is it used?

Okay, let me rephrase it for the sake of clarification:
If one will scoff at the study of language, how, assuming one doesn’t use language, will one scoff?

Is that’s what Mario saying? Please let me know.

If one will scoff at the study of language, how, save in terms of language, will one scoff? = Scoffing at language study can only be done in language itself.
