Annoying Dictionary *red underlining* beneath typed words in Safari

Question

Dear Mac Comrades,
How does one effectively get rid of the red underlining beneath words that I type online when using Safari (e.g., when typing Google search terms or filling out forms online)? I've looked through the Help menus for the Dictionary application that's part of Mac OS Tiger, but I cannot seem to turn it off!
I do NOT want to use the Dictionary within other applications, especially not Safari. It's annoying, distracting and interfering with my being able to read small typeface as a type. I hate the red underlining when it recognizes "misspelled" words.
Can the Dictionary application be deleted? I've tried putting it in the trash but the red underlining continues whenever I type online with the Safari browser. There must be some Apple Script that's preventing me from being able to purge the Dictionary altogether. How does one get rid of the darned thing? It's a terrible nuisance.
Any help would be appreciated!
Sincerely,
Vicki Landrum

Thanks you very much!!! BTW, I'd tried that before and for some reason could not de-select the option. Today it worked! (...I must have done something wrong before?). Again, many thanks!
