When should I use then and than?

The words "then" and "than" are often confused because they sound similar, but they have different meanings and functions in a sentence.

"Then" is an adverb that is used to indicate time or sequence. It is commonly used to show what happens next or to refer to a specific point in time. For example, "I will finish my work, and then I will go to the gym." In this sentence, "then" is used to indicate the order of events.

"On the other hand, "than" is a conjunction used to make comparisons. It is used to show a difference or to indicate a preference between two things. For example, "She is taller than her sister." In this sentence, "than" is used to compare the heights of two individuals.

To determine whether to use "then" or "than," consider the context and the purpose of the word in the sentence. If you are talking about time or sequence, use "then." If you are making a comparison, use "than." Remember that "then" relates to time, while "than" relates to comparison.
