I wonder whether there is any statistic data on morpheme-to-word ratio of certain languages. Is this something that can be and has been measured? The languages I am most interested in are the agglutinative languages Tamil and Turkish.
Could further an average morpheme-to-word ratio be justifiably called a constant of a given language, at least in a small timeframe?
How about an upper morpheme-to-word boundary? Does this exist as a "linguistic constant"? Are there comparative tables for different languages? Have specimen of words that actually exhaust this maximum capability of synthesis been recorded somewhere?
