जानो इंग्लिश- How to Use ‘Unless’ and ‘Until’ in the English Sentences

The words unless and until are often used together but their meanings are different, and often confused. Unless refers to a condition not being met while until refers to a time threshold not being crossed.

Definition of Until
The word until means, up to the particular time or event. It is used in sentences to denote how long the situation continues. Now let’s discuss where can we use ‘until’ in our sentences:
