Hi Judy,
Side note: if you are changing languages a lot, it's possible to set up
shortcuts that may be faster than using Tools | Language. It would
involve a little messing about with macros and putting some energy into
customizing, but is not so difficult.
However, for your actual problem:
Make sure you didn't accidentally turn on "Word 5.1 Menus". Look under
View to see if there's a check next to that option--uncheck if so, it
will vanish. Word 2004 has had a rash of complaints about 5.1 Menus
being enabled because the simple keyboard shortcuts control-5 and
control-8 turn them on. If that's the case, you are missing much more
than just Tools | Language--but that's a very common one that people notice.
If that isn't the problem:
If you go to Tools | Customize Toolbars/Menus, select the Menu Bar, and
click Reset, it should set all your main menus and built-in toolbars
back to
the default. (Reset will not solve the 5.1 menus issue, though)
If you have customized your menus or toolbars, you may want to explore the
Tools | Customize, Commands dialog, and drag the commands you are missing
back to the toolbars/menus yourself, rather than wipe out your
customizations by clicking Reset.
