Past Tense of “freeze”
The past tense of freeze is froze; the past participle is frozen.
Why “freeze” behaves this way
"Freeze" comes from Old English "freosan," whose ablaut class also produced "choose" (ceosan/ceas/coren) — its vowel shifts from ee to o to o-plus-en are a textbook example of the Germanic strong-verb system still functioning largely intact after more than a thousand years. The noun "frost" comes from the same root, essentially the past participle of "freeze" fossilized into a noun of its own, the same way "flood" derives from the verb "flow."
"Freeze" and "frost" being etymological siblings rather than coincidentally similar words explains why so much frozen-weather vocabulary in English clusters around this one root: "frozen," "frosty," "frostbite," and "defrost" all trace back to the identical Germanic source, unlike, say, "cold" or "ice," which come from entirely unrelated word families.
The common confusion
There's little confusion over froze versus frozen in isolation; the more common real mix-up is treating "freeze" and "frost" as unrelated synonyms rather than recognizing that "frost" is historically just "freeze" wearing a noun's clothing — useful context for spelling both correctly, since neither is a coincidental sound-alike.
How it's actually used
"Freeze" extends figuratively into finance (freeze an account, freeze prices), law (freeze assets pending trial), and psychology (freeze in fear, part of the well-known fight/flight/freeze stress response), none of which involve literal temperature but all of which keep the same froze/frozen conjugation. The command "freeze!" as a standalone imperative telling someone to stop moving instantly is a distinct, purely idiomatic use with no reference to temperature at all. Video and computer technology borrowed "freeze" for a screen or process that stops responding ("the app froze"), a distinctly modern extension with no connection to temperature at all, alongside the older cinematic term "freeze frame," describing a single paused image within otherwise moving footage. Ecology and geology also use "frozen" technically to describe permafrost — ground that has remained frozen continuously for at least two years — a precise scientific threshold distinct from the everyday sense of anything simply cold to the touch.
Across the tense system
"Frozen" functions as a fully independent adjective describing a fixed or unchanging state well beyond its literal sense — "a frozen smile," "frozen in time," "a frozen market" — a use so entrenched that dictionaries list it as a separate adjectival entry distinct from the verb's past participle, even though both are spelled and pronounced identically. Meteorology draws a precise technical line between "freezing" (temperature at or below zero Celsius) and merely "cold," and forecasters use the past participle constantly in warnings — "a hard freeze is expected overnight" — where "freeze" has shifted entirely into a noun naming the weather event itself rather than describing any object undergoing the process. Sports commentary borrows "freeze" to describe a player hesitating at a critical moment ("he froze at the free-throw line"), a psychological rather than physical sense that nonetheless conjugates identically to the literal meaning of ice forming.
Common real mistakes
A frequent error is using "freezed" as a mistaken regular past tense, especially among learners generalizing from more common regular verbs before they've internalized the strong-verb pattern. A subtler issue is overusing the figurative "frozen" in formal writing where a more specific word (suspended, halted, fixed) might read more precisely, since "frozen" as a metaphor has become so common it can feel like a filler word in business and legal prose. Writers occasionally also confuse "frozen" with "chilled" in culinary writing, where the two describe genuinely different states of food preservation rather than interchangeable synonyms.
Examples

Memory trick
Remember "freeze" as a direct relative of "frost" — the same root split into a verb and a noun centuries ago — and group its ablaut pattern with "choose/chose/chosen," which shifts its vowels the same way. If you can conjugate one, you can conjugate the other by matching the pattern.
