Can You Start a Sentence with “However”?

Although you may have heard otherwise, it’s fine to start a sentence with “however.” You just need to know when to use a comma because “however” can mean two different things, and if you don’t get the comma right, you risk confusing your readers.
If you use “however” at the beginning of a sentence without a comma, “however” means “in whatever manner” or “to whatever extent.”
-
However hard Anne Hathaway tried, she couldn’t liven up a robotic James Franco during the Oscars.
If you use “however” at the beginning of a sentence with a comma, “however” means “nevertheless”
-
However, I loved all seven of Anne’s Oscar dresses (plus the tuxedo).
