There are four basic types of conditional sentences, namely: actual conditional (called the zero conditional), likely conditional (called the first conditional), unlikely conditional (called the second conditional), and impossible conditional (called the third conditional).
1. Actual Conditional: This type is called the zero conditional sentences and it expresses what actually happens. It is used to state general truths, facts, or habits. Examples:
A. When a cub of sugar is put in water, it dissolves.
B. If it rains, the streets get wet.
2. Likely Conditional: This type is called the first conditional, and it expresses a likely future event or what could happen. Examples:
A. If it rains, I’ll not go to school.
B. If I meet him, I’ll give him the letter
3. Unlikely Conditional: This type is called the second conditional, and it expresses an unlikely event in the future. Examples:
A. If it rained, the streets would
get wet.
B. If I met him, I would give him the letter.
4. Impossible Conditional: This type is called the third conditional, and it expresses an impossible situation. It’s called an impossible situation because it never happened. Examples:
A. If It had rained, the streets would have been wet.
B. If I had met him, I would have given him the letter.
