Off and of are two short words that many learners confuse because they look similar and are pronounced quickly in everyday speech. Despite the similar spelling, their meanings are very different. One word usually shows separation or movement away, while the other shows a connection or relationship between things.
Off vs. Of

Common Mistake: “Off of”
