5 exercises — the phrasal verbs that describe what users and systems do: sign up, log in, opt in/out, set up, fill in, check out, back up, sync up. Essential vocabulary for writing user stories, API docs, and UX copy.
User action phrasal verbs — quick reference
Account lifecycle: sign up (create) · sign in / log in (enter) · sign out / log out (exit) · delete account
Onboarding: set up (configure) · fill in (complete a form) · opt in (choose to participate) · verify (confirm)
Commerce: add to cart · check out (complete purchase) · submit (send a form)
Data: back up (copy for safety) · sync up (align/update) · opt out (withdraw consent)
GDPR note: opt-in = explicit consent required · opt-out = enrolled by default, can leave

A UX designer writes in a Jira ticket: "The onboarding funnel has three steps: users sign up, set up their profile, then opt in to notifications." Match the phrasal verbs to their meanings.
Three key onboarding phrasal verbs:
Sign up = create a new account or register for a service. Notice the difference: you sign up (create) vs. sign in / log in (enter an existing account). "Sign up for a free trial." "Over 10,000 users signed up in the first week."
Set up = configure, establish, make ready for use. Not just installing — it includes configuring settings, filling in profile details, and preparing something to work. "Set up your workspace." "Set up two-factor authentication." "It takes 5 minutes to set up."
Opt in = voluntarily choose to participate or receive something. Especially important in GDPR/privacy context: features and marketing must be opt-in (user must actively choose to receive), not opt-out (enrolled by default unless they object).
Full onboarding phrasal verb chain: sign up → verify email → log in → set up profile → opt in to notifications → fill in billing details → check out → sync up with team

A backend developer is writing API documentation. Choose the correct phrasal verb: "Users can _____ their account at any time from Settings → Security. Their session will end immediately and they will need to _____ again to continue."
Sign out / log out and sign in / log in are the standard verb pairs for session management.
Sign out (also: log out) = end an authenticated session. "Sign out of your account." "If you sign out on a shared computer, no one can access your data."
Sign in (also: log in) = start an authenticated session with credentials. "Sign in with Google." "Log in to your account to continue."
Style conventions across platforms: • Apple products → sign in / sign out • Android / Google → sign in / sign out • Older enterprise software → log in / log out • Unix/Linux systems → log in / log out (or log on / log off)
Grammar note — separable phrasal verbs: "Sign out of your account" ✅ (prep + object) "Log out" ✅ (intransitive — often used without an object) "Log out of the system" ✅ "Sign out" without object ✅ (absolute use)
Related: sign off = end a communication: "I'll sign off for the day." Different from signing out of a system.

A QA engineer is writing a test case for a checkout flow. Which description uses phrasal verbs most accurately?
Check out and fill in are the standard phrasal verbs for ecommerce flows:
Check out = complete a purchase process (go through the final payment steps). Directly borrowed from the retail concept of checking out at a cash register. "Add to cart and check out." "The checkout process takes 3 steps." (Noun: "checkout" — no hyphen, no space.)
Fill in = write in or complete required fields. "Fill in the form." "Fill in your address." "Fill in all required fields before submitting."
Why not Option C or D? They use formal/technical register rather than the natural phrasal-verb register. QA test cases typically use active, plain language — "fill in", "check out", "click", "confirm" — to be clear and unambiguous.
Other e-commerce / form phrasal verbs: • add to (cart/wishlist): "Add to cart" — standard UI label • submit: technically not a phrasal verb but very common: "Submit the form" • back up: save a copy: "Back up your data before migrating" • check out vs. check in: check in = arrive/register (hotel, airport, standup: "Check in on Jira")

A DevOps engineer writes a runbook step: "After the migration, all services will automatically sync up with the new database. Users should back up any local data before the maintenance window." What do sync up and back up mean here?
Sync up = synchronise — bring two or more systems, devices, or people to the same consistent state. Can be technical or interpersonal: "sync up the databases", "sync up with your team", "sync up your calendar."
Back up = create a copy of data so it is protected and recoverable. Critical IT safety habit: "Back up your data before upgrading." "The backups run every 24 hours." (Noun: "a backup" — one word, no hyphen.)
Back up variants in IT and plain English: • back up data = create a safety copy • back up a claim = support with evidence: "Can you back that up with metrics?" • back up traffic = cause congestion: "The queue backed up after the server went down." • be backed up = have a lot of work queued: "The support queue is totally backed up."
Sync up variants: • sync up databases = ensure data consistency • sync up with someone = align on status, share updates (replaces "let's have a quick meeting") • in sync = aligned and consistent: "Are the dev and staging environments in sync?"

A product manager is describing a GDPR compliance feature: "Users should be able to _____ from marketing emails with a single click, and the preference should _____ with our CRM within 24 hours."
Opt out = choose to stop participating in something; withdraw consent or remove yourself from a group or list. Opposite: opt in (choose to join/participate). The pair is especially important in GDPR and privacy law contexts.
Sync up = here used for data synchronisation between systems: "sync the preference with our CRM" means the unsubscribe choice should be reflected in the CRM database within 24 hours.
Opt in / opt out — the GDPR distinction: • Opt-in (explicit consent model): users must actively choose to receive marketing. Default = not enrolled. Required by GDPR for most marketing communications. • Opt-out (soft opt-out): users are enrolled by default but can leave. Allowed in limited scenarios (e.g., existing customers, legitimate interest). • Writing in UI/UX: "Opt out of marketing emails" (button text) · "You can opt out at any time" (privacy policy language)
Why the other options are wrong: • "Log out / merge in" — log out ends a session; merge in combines branches — neither fits • "Sign off / back up" — sign off means approve; back up means copy data • "Phase out / roll out" — phase out is for retiring a product; roll out is for deploying to users
