Vanessa teaches “double check,” a useful expression for verifying information or confirming a plan when you are not completely sure. She begins with an everyday question: “Are you available tomorrow?” If you have forgotten what is on your schedule, you can say, “Let me double-check.” The phrase means check something again to make sure it is correct or to refresh your memory. It is normal to be uncertain sometimes; the expression gives you a polite way to take a moment before answering.
You can double-check your own calendar or schedule: “I need to double-check my schedule.” You can also double-check with another person when a plan affects them. For example, if you need to confirm whether your husband wants to see a movie, say, “Let me double-check with my husband,” or “Let me double-check with him.” This signals that you will ask the person before giving a final answer. Vanessa notes that people may want you to check with them before committing them to an activity.
The expression works in many situations: confirming whether you are free, checking that you completed lesson materials, or making sure you remember an appointment. “Double-check” may be written with a hyphen when it is a verb or modifier, while “double check” is common in casual text. In speech, both forms sound the same. “Let me double-check” is especially useful as a brief, considerate response when you need a little time.
Vanessa invites viewers to think about something they often need to double-check because they forget it. To practise, name the thing and the person or source you will check: “I need to double-check my calendar,” or “I’ll double-check with my partner before I say yes.” This expression helps avoid mistakes and premature commitments, while keeping everyday conversation polite and natural.
The phrase is particularly helpful when making plans with other people because it avoids a guess or an accidental yes.
