Conditionals - Zero conditional


Zero conditional

"Zero conditional" refers to conditional sentences that express a factual implication, rather than describing a hypothetical situation or potential future circumstance. The term is used particularly when both clauses are in the present tense; however such sentences can be formulated with a variety of tenses/moods, as appropriate to the situation:

  • If you don't eat for a long time, you become hungry.
  • If the alarm went off, there's a fire somewhere in the building.
  • If you are going to sit an exam tomorrow, go to bed early tonight!
Here are some more examples:

  • If people eat too much, they get fat.
  • If you touch a fire, you get burned.
  • People die if they don't eat.
  • You get water if you mix hydrogen and oxygen.
  • Snakes bite if they are scared
  • If babies are hungry, they cry
