This question is very similar to Extendible equals sign but the solutions given there do not apply immediately.
At times I woud like to clarify the nature of a mathematical congruence. So I have defined in my preamble
\newcommand*\morph[1]{\underset{\mbox{\tiny #1}}{\cong}}
So I can write things like \morph{diff}
and \morph{hom}
to differentiate between different congruences. But even with the \mbox
content set to \tiny
, the text is still wider than the congruence sign. Any ideas?

One could always use
\resizebox
to stretch the symbol.
