Write as a Function, and checkout the last note on the Function Help page.
f[1,3]:= Function[y, ..., {HoldFirst}]

I am building a family of functions, parametrized by 2 variables.
These functions take one argument, so i have these definitions:
f[1,3][y_]:=....
f[1,2][y_]:=....
f[1,3][y_]:=...
f[2,1][y_]:=....
etc. As you see it's a case of subvalues being defined.
The problem is that I also require that the y argument should be held.
That is the functions should have something like
Attributes[f[m,n]]={HoldFirst};
But this is not acceptable to Mathematica, since Attributes only takes
symbols.
Even using
Attributes[f]={HoldAll};
does not seem to work.
So , how can i keep the argument y held?
