    In[1]:= FullForm[x->y*z^w]

    Out[1]//FullForm= Rule[x, Times[y, Power[z, w]]]

    In[2]:= x\[UnionPlus]y\[RightTee]z

    Out[2]= x ⊎ y ⊢ z

There's no reason your programming language shouldn't be able to tell you what these things are called in English without an external reference.

Some operators are so abstract that they don't really have a good name.

Eg if you are talking about groups in general, how do you pronounce the group operation ∘? At uni, we usually just called it Kringel.

The name can be arbitrary, as long as it's unambiguous. By the way, here's what mathematica says when I copy paste that and enter x∘y: SmallCircle[x,y]

Also fun:

    In[3]:= SpokenString[x\[SmallCircle]y]
    Out[3]= "SmallCircle of x and y"

Which can be turned in to sound:

    Speak[x\[SmallCircle]y]

Actually, it's not even unambiguous. In some sense, it's like an unbounded variable.
