In conditional clauses, the term “otherwise” is used to indicate the alternative outcome or consequence that would occur if the condition stated in the main clause is not met. It serves to highlight the result that will happen if the specified condition is not fulfilled. By using “otherwise,” the speaker or writer can clarify the potential implications of the condition not being satisfied, providing contrast and emphasizing the contrast between the two possible outcomes.

For example:

“Study hard, otherwise you will fail the exam.”

In this sentence, “otherwise” signals the consequence of failing the exam if the condition of studying hard is not fulfilled. It helps to make clear the cause-and-effect relationship between the condition and the potential result, thereby adding clarity and emphasis to the conditional statement.

In summary, “otherwise” in conditional clauses acts as a linguistic tool to articulate the potential outcomes of a given condition and underscore the importance of fulfilling that condition to avoid the specified consequence.
