I want to know the answer to the following question:
When did Max Weinrich write "A shprakh iz a dialekt mit an armey un flot"?
All the background I'm provided with is that "The Yiddish linguist Max Weinreich published the expression, A shprakh iz a dialekt mit an armey un flot ("אַ שפּראַך איז אַ דיאַלעקט מיט אַן אַרמײ און פֿלאָט"‎:". Is that enough to answer the question?
Answer: no
