Figure out

The go-to phrasal verb for mental problem-solving: understand, solve, decide — and “figure someone out.” With programming and client examples, the figure-out-vs-sort-out distinction, a separability + question-word note, and a quiz.

Overview

Figure out is the classic American-flavored phrasal verb for mental problem-solving. Where sort out is about doing (fixing, arranging), figure out is about understanding — the moment in your head when something clicks.

Grammar preview: it’s separable — figure out the problem / figure the problem out / figure it out — and loves question words: figure out why / how / what / where…

Parts of speech

Figure out is a verb only — it has no common noun or adjective form.

As a verb — “figure out”

Meaning: to understand, solve, or decide.

5 examples
  • “I figured out why the app crashes.”
  • “Give me a minute to figure out the math.”
  • “We’re still figuring out the schedule.”
  • “I can’t figure him out.”
  • “Let’s figure out what to do.”

Unlike set up or check out, there’s no “a figure-out.” Keep it as a verb.

Understand / discover the reason

= understand · determine · discover.

  • “I finally figured out why the app crashes.” (discovered the cause)
  • “I can’t figure out what she meant.” (understand)

Solve a problem mentally

= solve · work out · calculate.

  • “Give me a minute to figure out the math.” (calculate)
  • “We figured out a way to cut costs.” (found a solution)

Decide / plan

= decide · determine · plan.

  • “I’m still figuring out where to relocate.” (deciding)
  • “Let’s figure out the schedule for next week.” (plan / decide)

Figure someone out

Understand a person’s character or motives.

  • “I can’t figure him out — one day friendly, next day cold.” (understand his character)

In programming

At work
  • “Spent two hours figuring out why the webhook wasn’t firing — turned out to be a trailing slash in the URL.”
  • “I can’t figure out this legacy code. Who wrote this?” (understand)
  • “Once I figured out how their auth flow works, the integration took 20 minutes.”
  • “Still figuring out the best DB schema for this feature.” (deciding on)
  • “Claude helped me figure out the race condition.” (diagnose / understand)
figure out = diagnosis, [sort out](/expressions/phrasal-verb/sort-out) = the cure

“I figured out the bug (found the cause), then sorted it out (fixed it).” Figure out is understanding; sort out / fix is doing.

Everyday life

  • “I’m trying to figure out how this washing machine works.” (understand)
  • “We need to figure out what to get Mom for her birthday.” (decide)
  • “It took me a while to figure out the metro system in a new city.”
  • “I haven’t figured out what I want to do long-term yet.” (life plans)

Client phrases to steal

Natural client-communication lines
  • “I’ve figured out the root cause — fix incoming within the hour.”
  • “Let me figure out the best approach and get back to you with an estimate.”
  • “Still figuring out why prod behaves differently from staging — will update you by EOD.”
  • Figured it out! The API key had expired.” ✅

Grammar: the four patterns

Four patterns cover almost every use of figure out.

Formula 1 — figure out + noun (object)

figure out + [noun phrase]

  • I figured out the problem.
  • She figured out the answer.
  • We figured out a solution.

If the object is a pronoun, it must go in the middle: figure it out ✅ / figure out it ❌ · figure him out

Formula 2 — figure out + question word + clause

figure out + why / how / what / where / when / who + subject + verb — the most common pattern in real speech.

  • I figured out why the app crashes.
  • I can’t figure out how this works.
  • Let’s figure out what we need.
  • I figured out where the bug is.
  • She figured out who sent the email.
Use normal word order after the question word

After the wh-word, use statement order, NOT question order:

  • ✅ I figured out why the deploy failed.
  • I figured out why did the deploy fail.

This is a classic mistake for Ukrainian / Russian speakers.

Formula 3 — figure out + question word + to-infinitive

figure out + how / what / where / when + to + verb — used when the subject is the same person.

  • I figured out how to fix it.
  • We need to figure out what to do.
  • I can’t figure out where to put this file.
  • Let’s figure out when to schedule the call.
Formula 4 — figure out + that-clause (less common)
  • I figured out (that) the API key was expired. — that is usually dropped in speech.
Quick comparison
  • + noun → figure out the bug
  • + it / them → figure it out
  • + wh- + clause → figure out why it fails
  • + wh- + to-verb → figure out how to fix it
  • + that-clause → figure out that it was a typo
