How to Give Estimates and Approximations in English at Work

ESL English learning: Master vague expressions and approximation vocabulary for giving rough estimates in standups, RFCs, and technical planning meetings.

Pronunciation Guide: Approximation Vocabulary

These approximation terms are frequently mispronounced by non-native speakers. Pay attention to stress patterns and common error traps.

approximately /əˈprɒk.sɪ.mət.li/

a-PROX-i-mat-ly

Saying 'ap-pro-xi-MATE-ly' with stress on fourth syllable

in excess of /ɪn ɪkˈses ɒv/

in ex-CESS of

Pronouncing 'excess' as 'ex-CESS' instead of 'EK-sess' (noun stress)

smattering /ˈsmæt.ər.ɪŋ/

SMAT-ter-ing

Saying 'sma-TER-ing' with stress on second syllable

region /ˈriː.dʒən/

REE-jun

Pronouncing as 're-GI-on' with hard G

smidgen /ˈsmɪdʒ.ən/

SMIJ-en

Saying 'smid-GEN' with stress on second syllable

Why Approximation Language Matters in Tech

In tech, you're constantly asked for estimates — in standups, planning meetings, Slack threads, and design docs. The problem? Estimates are inherently uncertain, but stakeholders often treat them as commitments.

Using the right approximation vocabulary helps you communicate uncertainty clearly. It protects you from over-promising while still giving useful information. This is a core professional skill that many non-native speakers struggle with.

  • Standups: 'It'll take a week or so to finish the refactor.'
  • Planning meetings: 'We're looking at somewhere in the region of 3 sprints.'
  • RFCs: 'Implementation time is approximately 4-6 weeks.'
  • Slack: 'Give or take a few hours, we should have the fix deployed by EOD.'

Key Approximation Vocabulary for Tech Professionals

Different expressions carry different levels of formality. Choosing the right one depends on your audience and context — Slack messages to teammates vs. a formal RFC for leadership.

ExpressionRegisterTech Workplace Example
give or takeInformal'The migration will take 3 days, give or take a few hours.'
or soInformal'We'll need a week or so to complete code review.'
more or lessInformal'The performance issue is more or less resolved.'
somewhere in the region ofNeutral'Latency is somewhere in the region of 200ms.'
approximatelyFormal'The project requires approximately 6 developer-weeks.'
in excess ofFormal'Memory usage was in excess of 8GB during peak load.'
quite a fewInformal'Quite a few tests are still failing in CI.'
a smattering ofNeutral'We had a smattering of edge cases to handle.'

Register Awareness

Use 'approximately' and 'in excess of' in RFCs, design docs, and emails to leadership. Save 'give or take' and 'or so' for Slack and casual standup conversations.

Informal Slack vs. Formal Documentation

The same estimate needs different language depending on where you're communicating. Here's how to adapt your approximation vocabulary across contexts.

Slack / Standup (Informal)RFC / Design Doc (Formal)
It'll take a week or so.Implementation is estimated at approximately one week.
We're looking at 500 requests per second, give or take.Throughput is expected to be in the region of 500 RPS.
Memory usage went over 8GB.Memory consumption was in excess of 8GB.
Quite a few edge cases broke.A notable number of edge cases were identified.
The latency is more or less acceptable now.Latency has been reduced to acceptable levels.

Softening Estimates: 'A Bit' and 'A Bit of a'

When discussing problems or uncertainties, native speakers often soften their language with 'a bit' (with adjectives) or 'a bit of a' (with nouns). This makes your communication less alarming while still being honest.

  • 'The deployment is a bit delayed.' (adjective: delayed)
  • 'We're in a bit of a bind with the third-party API.' (noun: bind)
  • 'The timeline is a bit optimistic.' (adjective: optimistic)
  • 'There's a bit of a bottleneck in the data pipeline.' (noun: bottleneck)

Cultural Note

In Anglo tech culture, softening language is expected. Saying 'We have a problem' sounds more alarming than 'We have a bit of a problem.' The latter signals the same issue but with less panic.

Vague References: 'Or Something,' 'Or Whatever,' and 'Along Those Lines'

When brainstorming solutions or suggesting alternatives, you don't always need to be precise. These expressions let you gesture toward a category of solutions without committing to specifics.

ExpressionUsageExample
or somethingSuggests alternatives'We could use Redis or something for caching.'
or whateverCasual, any option'Just spin up a Lambda or whatever works.'
things like thatSimilar items in category'We need to handle rate limiting, retries, things like that.'
or something along those linesFitting the description'Maybe a pub/sub architecture or something along those lines.'
or words to that effectParaphrasing someone'He said the architecture was 'overly complex,' or words to that effect.'

Common Mistakes: What We Hear vs. Better English

Non-native speakers sometimes misuse approximation expressions or choose the wrong register. Here are corrections based on real patterns heard in tech workplaces.

❌ Heard at Work✅ Better English
The sprint is more or less 2 weeks.The sprint is about 2 weeks. (Don't use 'more or less' with fixed durations)
She is more or less 30 years old.She's about 30. (Don't use 'more or less' with ages)
It will take approximately a week, give or take.It will take a week, give or take. (Don't mix formal and informal)
We have stacks of bugs in production.We have quite a few bugs in production. ('Stacks of' is too casual for problem reports)
The cost is in the region of expensive.The cost is somewhere in the region of $50,000. (Use with numbers, not adjectives)
