put
putted
puts
will put
Zero conditional sentences express general truths and use the present simple in both clauses. "If you put sugar in tea, it tastes sweet" follows this pattern, making "put" the correct form. Options like "will put" and "putted" are grammatically incorrect here. For more on zero conditionals see .

Cheat Sheet

  1. Zero Conditionals for Universal Truths -

    Zero conditionals express facts and habits using the structure If + present simple, present simple (Cambridge Dictionary). For example: "If you heat water, it boils." Practice this in your conditional sentences quiz to solidify cause-and-effect patterns.

  2. First Conditional for Real Future Possibilities -

    First conditionals talk about likely future events with If + present simple, will + base verb (Purdue OWL). For instance: "If it rains tomorrow, I will stay home." Remember the mnemonic "Will or Won't in the future" to ace the first conditional quiz section.

  3. Second Conditional for Hypothetical Present/Future -

    Use the second conditional for unlikely or imaginary situations: If + past simple, would + base verb (British Council). Example: "If I spoke French, I would work in Paris." A handy trick is "Past tense + would = daydream mode."

  4. Third Conditional for Past Regrets -

    Third conditionals reflect past hypotheticals with If + past perfect, would have + past participle (Oxford University Press). For example: "If I had studied harder, I would have passed the exam." Listen for the "had" and "have" to nail this in your conditional sentences quiz.

  5. Mixed Conditionals and Inversion Tips -

    Mixed conditionals combine time frames, e.g., If + past perfect … would + base verb: "If I had trained more, I would be fitter now" (University of Manchester). You can invert third conditionals by dropping "if": "Had I known, I would've helped." Try these in a conditionals grammar quiz for advanced practice.
