Often it is needed to add Greek letters/symbols to microsoft word documents. If you want to add Greek Letters to Microsoft Word Documents follow this procedure.
Open Microsoft word Select Insert from the top menu and Select Symbol
Once you have the symbol window Select Symbol from the font drop down

An easier way is to type the letter similar to the Greek letter (for example, “a” for alpha), highlight that the letter, and then change the font to symbol.
