The first parameter of infl

I think that's better too, but I've always added the language as well. I'm not really sure what script to use if the language is not specified, though.

The first parameter could only be left blank if the language is English, otherwise the surrounding element wouldn't have the lang parameter set. {{{{{1|en}}}/script}} would probably work.

That would work if people are typing {{infl}}, but does anyone ever type (say) {{infl||verb forms}}? (I wouldn't have thought so, but I wouldn't have thought anyone just typed {{infl}}, either . . .)

I doubt anyone would leave {1} blank but specify {2}.
