"syntagma"? (referenced as one possible incorrect pluralization) - Steve and 4 other people

"syntaxes" - OCoG of FF, Jimminy

I agree with Jimminy. - Stephen Mack

And I know it's an example, but I want to nit. I'd probably call them in that specific case, "Python", "branches of Python syntax", assuming you're talking about <2.6, 2.7, and 3.x. Since it is primarily one syntax, with breaking but minimal revision. - OCoG of FF, Jimminy

Or you could be talking about idiomatic styles, because their are several thanks to the flexibility of the language. - OCoG of FF, Jimminy

grep -i syntaxes /usr/share/dict/words -- this means that "syntaxes" is not in the standard Linux dictionary, and thus, shows up as a misspelled word. - Steve and 4 other people

The earlier syntaxis was disrupted by synuber and left us with syntaxes. - Micah

The wages of syntax are deathtax. - Stephen Mack

It may be syntactics, or just syntax. Syntax is the group of syntactic elements, which is pluralized to syntactics (even though it can also be used in the singular). So syntax and syntactics are roughly equivalent in meaning and purpose, and could show in substitution a shared singular/plural form. Of course, syntactics is apparently not a word according to Chrome's dictionary. - OCoG of FF, Jimminy

Syntactics refers to the domain of syntax in general. Syntaxes refers to multiple individual syntactic systems. - Sean McBride
