Etymology
Origin of chiefly
Explanation
Use the adverb chiefly to mean "mostly" or "primarily." You could say your history class is chiefly focused on 18th century American history if all your teacher wants to talk about is the American Revolution. If you usually ride your bike to work, you can say, "I'm chiefly a bicycle commuter," and your neighbor's obituary might mention that she'll be chiefly remembered for her work as a civil rights activist in the 1960s. You can also use chiefly to mean "for the most part," when you talk about the contents or composition of something: "My granola is chiefly almonds." The word comes from the Old French chief, "principal" or "first."
