1. What Are Conditional Sentences? – Meaning and Definition

Conditional sentences are sentences that express a condition and its result. They often consist of two parts:

• • The if-clause (condition): Expresses the condition that must be met.
  • The main clause (result): Explains the result if the condition is met.

Definitions:

• • Oxford Learner’s Dictionary: “A sentence that begins with ‘if’ or ‘unless’ and expresses a condition.”
  • Collins Dictionary: “A conditional sentence describes a situation that will only happen if something else happens first.”
  • Cambridge Dictionary: “A sentence often starting with ‘if’ or ‘unless’ that expresses a condition and its dependent outcome.”

2. Importance of Conditional Sentences in Communication

Conditional sentences are essential because they help:

• • Express possibilities: “If it rains, we’ll stay indoors.”
  • Discuss hypothetical situations: “If I were a millionaire, I’d buy a yacht.”
  • Plan actions based on conditions: “If you finish your homework, you can watch TV.”
  • Express regrets or alternate outcomes: “If I had studied harder, I would have passed.”
