Real output from an actual run on the phrase below, unedited.

The phrase, and where it came up

“Let's not boil the ocean.” My manager said this when we were talking about everything we wanted to include in the first version of a project.

Real run, 2026-10-07 — the tool's own built-in example.

What kind of phrase is it?

• Idiom: the phrase carries a fixed figurative meaning that cannot be derived from the individual words.
• Metaphor: the deliberately impossible image of boiling an entire ocean is what gives the phrase its force — understanding the image helps the meaning land.
• Workplace phrase: used in professional settings to push back on scope creep.

Plain meaning

Don't try to do everything at once — keep the scope manageable.

What it means here

Your manager is suggesting that the first version of the project should include less, not everything the team has discussed. The implication is: narrow the scope now and add more later.

The tone

Mildly cautionary, collegial — it frames a constraint as shared common sense rather than a direct rejection.

Say it plainly

Let's not try to include everything in this first version — let's keep the scope realistic.

Why this phrase?

The image is deliberately impossible: boiling an entire ocean is a task so vast it could never be completed. That impossibility maps onto the idea of taking on an unrealistically large scope — something that sounds productive but cannot actually be finished.

The edge

It tells you when the phrase genuinely could mean two different things, instead of picking one.

Good to Know

• Context changes everything — the same words can be literal or figurative depending on the situation, and What's That Mean? classifies the use, not just the words
• If it comes back genuinely ambiguous, that's the honest answer, not a failure — add more context to narrow it down
• For jargon, it focuses on what the term means and skips manufacturing cultural history or tone that ordinary technical language doesn't have
• The cross-language equivalent is honest when nothing tidy exists — it won't invent an idiom just to give you a neat answer

Questions people ask

What does “let's not boil the ocean” mean?

It means don't try to do everything at once — keep the scope manageable. It's an idiom built on an impossible image (no one can boil an ocean), and at work it's usually a gentle way of saying a plan has grown too big. The real example on this page shows the full breakdown What's That Mean? gives for it.

How can I tell whether a phrase is an idiom, slang, or jargon?

An idiom has a fixed figurative meaning you can't work out from the words. Slang is informal and often tied to a group or a moment. Jargon is the technical vocabulary of a field and usually means exactly what it says to insiders. What's That Mean? names which kind a phrase is — sometimes more than one — and says why.

Can it explain office phrases like “circle back” or “take this offline”?

Yes. Workplace phrases are one of the kinds it recognizes. Paste the sentence they appeared in, because the same phrase can be routine in one meeting and pointed in another, and the meaning it gives you is for that situation.

What if a phrase could mean two different things?

It says so and lists the possible readings, rather than picking one and sounding sure. It also tells you what extra context would settle it — usually the sentence before, or who said it.

Can it help with phrases from another language?

It answers in any of DeftBrain's 13 languages, and it can suggest a phrase in another language that does the same job. When no tidy equivalent exists, it tells you that rather than inventing one.
