Some times add to dictionary is there. Sometimes it is not. Microsoft choose when am allowed to add to dictionary. As to Charles. Your link is irrelevant as you never read my original post. If you had, you would not have given advice on forene lanquage prrofing tools or given me a link to Suzans link which is over 10 years old and not relevant to the modern word.

I I said from the start (Charles). One simply RIGHT clicks on a word. For your information this produces a pop up menu where add to dictionary is shown. Try it out for yourself.

This has been standard since word used a mouse and before there were foregn language proofing tools. Before you were born perhaps.
