You probably hear it as often as I do: “I verbally told him to….” The command might be to get out of the car, open her purse, hand over his driver’s license, or something similar.
But verbal is meaningless in sentences like this. Verbal means “using words.” It’s not a synonym for oral. Verbal communication can include writing, texting, emailing, and writing in chalk on a sidewalk.
When you’re careful to use oral for spoken commands, you portray yourself as a professional – a good thing!
