''Elementary translation''

A mapping $\phi$ of an [[algebraic system]] $\mathbf{A} = (A,\Omega)$ into itself, of the form
$$
\phi : x \mapsto F(a_1,\ldots,a_{k-1},x,a_{k+1},\ldots,a_n)
$$
where $F$ is the symbol of a basic operation in $\Omega$ and $a_1,\ldots,a_n$ are fixed elements of the set $A$.

The terminology "elementary translation" is also used: as are "algebraic function" (of one variable) or "polynomial".
