@ Aga Thanks for misunderstanding me so badly and then immediately insulting me so nicely 
I had written: The question of why “y” is one of the most frequent suffixes can only be explained by absorption.
That is exactly what you are applying here as well—y as absorption.
Then I shifted the topic to frequency analysis: a frequency analysis would, in principle, merely have established that there is no equivalent. If one were to attempt this with “y” in Latin, it would fail, as has indeed happened often enough.
This refers to frequency analysis, not to absorption - the comparison in the post is precisely about that frequency analysis...
