Usage of 'commas' vs 'commata'

I've learned quite recently, that plural form from comma is commata (but commas is also correct, such as index-indices-indexes). I've learned the rule for German, and I've checked the English version too.

This is the first time I've consciously seen that word (I could came across it before, but I haven't notice). What is the usage of that 2 plural forms? Which is more recent in professional literature (for blogs/twitter&co I'd guess, 'commas')?

Should I, as non-native speaker, making many common mistakes, use such 'finesse' plural forms, or it sounds funny in such context?

Solution 1:

Use commas, not commata. The latter is simply not used by native speakers.

Take a look, for example, at Google's Ngram Viewer on commas versus commata:

It's not even close.
