常見的用法如經常遲到英文可以說 often late、經常失業英文可以說 often unemployed、經常出差或經常去商務旅行英文可以說 often go business trip、經常吵架英文是 often quarrel、經常浪費英文可以說 often wasted、經常開會英文是 often meet、經常請假英文是 often leave、經常抱怨英文可以說 often complain ... 等，用途相當廣泛。
其實我們中文說的經常也代表著高頻率的意思，所以也可以用 frequently（聽發音）這個單字來表示，例如經常問的問題英文可以說 frequently asked questions、經常使用英文是 frequently used。
