These two words come from the same verb freeze, but they behave in completely different ways depending on the tense and sentence structure. You’ll hear people say things like “I have froze it” or “The lake was froze,” and those errors stick because the words sound similar.
This guide clears up every part of the confusion. You’ll learn when to use froze, when to use frozen, how the perfect tenses work, why this verb changes its vowels, and how to remember the difference forever.
Let’s dive in and get your grammar solid as ice.

- Frozen = used with helping verbs or as an adjective.
You’re about to see exactly how each one behaves.
When to Use “Froze”: The Simple Past Tense
Whenever the action already happened, and there’s no helping verb, you use froze.
Think of “froze” as the answer to the question:
➡️ “What happened?”
Examples
- The water froze overnight.
- I froze the leftover curry.
- She froze when she heard the loud noise.
- My computer froze during the update.
Notice what all these sentences have in common:
- One action
- Completed in the past
- No “has,” “have,” “had,” or “will have”
That’s the key.
Common Learner Mistakes with “Froze”
People often misuse “froze” in sentences where a helping verb appears.
❌ I have froze the chicken.
✔️ I have frozen the chicken.
❌ The pipes were froze last night.
✔️ The pipes were frozen last night.
When you see a helping verb, the sentence always needs frozen, not froze.
When to Use “Frozen”: The Past Participle
You use frozen when:
- There’s a helping verb
- You’re describing a state rather than an action
- You’re writing in a perfect tense
- You’re using it as an adjective
Frozen = past participle
Past participle = needs a helper
In simple words:
➡️ “Frozen” never stands alone in a verb phrase.
Examples
- The lake has frozen solid.
- The food was frozen when I bought it.
- I’ve frozen all the berries.
- He had frozen the pipes by accident.
Frozen as an Adjective
Sometimes frozen doesn’t function as a verb at all. It acts as a describing word.
Examples:
- frozen pizza
- frozen lake
- frozen heart (metaphorical)
- frozen screen
You wouldn’t say froze pizza, right?
That’s how you know the word is forming an adjective.
Using “Frozen” in Perfect Tense Constructions
Perfect tenses describe actions connected to another point in time. They always use a helping verb.
And that’s why frozen shows up here every time.
Present Perfect (“has/have frozen”)
This tense connects the past to the present.
Formula:
has/have + frozen
Examples:
- The wind has frozen the pond.
- She has frozen the vegetables for the week.
- I’ve frozen too many meals.
Past Perfect (“had frozen”)
This tense shows something that happened before another past event.
Formula:
had + frozen
Examples:
- The pipes had frozen before the plumber arrived.
- She had frozen the strawberries before the storm hit.
- They had frozen all the fruit by winter.
Future Perfect (“will have frozen”)
This tense expresses an action that will be complete by a future time.
Formula:
will have + frozen
Examples:
- By morning, the roads will have frozen.
- The pond will have frozen by December.
- The fish will have frozen solid by then.
How “Frozen” Works in Passive Voice and Adjective Form
Many learners confuse passive voice with adjectives, because both use “frozen.”
Here’s the difference.
Frozen in Passive Voice
Passive voice flips the usual sentence structure.
Formula:
be + frozen
Examples:
- The food was frozen by the factory.

- The road gets frozen every year.
Frozen as an Adjective
Here’s how you can tell when “frozen” is an adjective:
- You can replace it with another adjective (e.g., cold, hard)
- There’s no action happening
- It’s describing a state, not an event
Examples:
- frozen foods
- frozen water pipes
- frozen vegetables
Quick Test:
If “very” can go before it, it’s an adjective.
✔️ very frozen lake
❌ very froze lake

Historical Snapshot: Where “Freeze” Came From
The verb “freeze” comes from Old English “frēosan,” meaning “to turn into ice.”
The past tense was frēas and the past participle was froren.
These old forms evolved through typical vowel-shift patterns into the modern:
- freeze
- froze
- frozen
This is why English irregular verbs don’t always “follow the rules.” They follow history.
