Confused About Zero vs. First Conditional: Which Should I Use When Talking About Habits?

Asked byPunctuation PaulPosted Mar 22, 2026 5:17 AM3 answers14 upvotesCanonical URL

I'm writing a short story and trying to describe what usually happens when my character gets home from work. I'm not sure if I should use the zero or first conditional in these situations. For example, should I write: "If she gets home early, she cooks dinner" or "If she gets home early, she will cook dinner"?

I keep seeing both forms in different grammar books, but I’m not sure when to use each one. Is there a clear rule about when to use zero or first conditional, especially in stories or everyday conversations? Would love some clarification!

To decide between zero and first conditional, focus on the pattern each one expresses:

Zero Conditional = Facts & Habits (General Truths)
Pattern: If + present simple, present simple
Use this when describing things that always happen, habits, or rules.

First Conditional = Real Possibilities (Specific Cases in Future)
Pattern: If + present simple, will + base verb
Use this for likely future situations and their results.

Examples:

  • Zero: If she comes home late, she orders takeaway. (This is her usual habit.)
  • First: If she comes home late, she will order takeaway. (Talking about what could happen tonight.)

Try it yourself:
Rewrite this sentence for both conditional types:
“If he finishes work on time, he _____ (go) to the gym.”

  • Zero: If he finishes work on time, he goes to the gym.
  • First: If he finishes work on time, he will go to the gym.

Tip: If you’re describing a habit in your story, use the zero conditional. Use the first conditional when you want to highlight a possible one-time action in the story’s future.

Imagine your character gets home from work most days—think about what happens every time versus what might happen on one occasion.

  • Every time (zero conditional): Use this for routine or predictable outcomes.

    • Example: If she feels tired, she makes a cup of tea. (This is her regular behaviour.)
  • One time (first conditional): Use this to talk about a possible future event, not a habit.

    • Example: If she feels tired tonight, she will make a cup of tea. (You’re talking about a potential action tonight.)

Corrective tip: Ask yourself: “Is this something she always does, or just something she might do later?”

Try this: Write two versions:

  • Habit: If he arrives before six, he watches the news.
  • Possibility: If he arrives before six today, he will watch the news.

When choosing between zero and first conditional, compare how the meaning changes:

  • Zero Conditional: Used for things that are always true, or happen regularly (habits, scientific facts).

    • Ex: If Mark leaves the office early, he takes the bus home. (This is something that always happens, a routine.)
  • First Conditional: Used for a possible (not certain) event in the future; often for promises, offers, warnings, or predictions.

    • Ex: If Mark leaves the office early, he will take the bus home. (This is about today or a specific future possibility.)

Corrective feedback: If you notice you always use "will" after "if," check: Are you talking about a specific future event? If not, you probably need zero conditional.

Practice: Write two similar sentences for your character, one showing a habit and one showing a specific situation. E.g.:

  • Habit: If she gets stressed, she listens to music.
  • Specific: If she gets stressed tomorrow, she will listen to music.
