Usage and Grammar
Q. Is the word “how” necessary in sentences such as “Learn how to bake breads and cakes”? In some cases, it sounds better with the word “how,” but it seems unnecessary in this case.
A. Learning to do something isn’t necessarily the same as learning how to do it. If I say “I learned to turn off my cell phone at the opera during act 4 of Otello while Desdemona was singing that soft, wrenching aria and hoping Otello wouldn’t strangle her,” it doesn’t mean I was learning how to turn it off. So use the word “how” whenever it’s needed to make your meaning clear.
