English grammar
for work

Workplace grammar isn't about rare rules. It's about a short list of errors that appear again and again in CVs, emails, chats and reports, and that make writing unclear or look careless. The main ones are verb tenses; articles (a, an, the); prepositions (in, on, at, for); subject-verb agreement; countable and uncountable nouns; word order in questions; and run-on sentences that join several ideas without punctuation.

India's adults are stronger at writing than listening: EF's English Proficiency Index 2025 gives India a writing score of 504, against a national average of 484.¹ But repeated small errors still stand out to employers. Grammar matters most in jobs that live on writing — AmbitionBox lists content writers at a typical ₹3.9–4.3 lakh and technical writers at ₹8.1–8.9 lakh.²³ At B2 on the Council of Europe's CEFR scale, users "produce clear, detailed text"; at C1, "well-structured" text with controlled use of organisational patterns.⁴

Table: Tenses at work (editorial)

• A list of your five most frequent errors
• A proofread CV and cover note
• Three work emails rewritten correctly
• Practice with tenses and articles
• A habit of reading aloud before sending
• A verified English Grammar certificate

Check every line for tense consistency (past tense for past roles), articles and prepositions. Ask someone with strong English to review it. One typo can undo a strong profile.

"Can you correct this sentence?"

Read it carefully, fix the error and explain the rule briefly.

"Write a short email to a client about a delay."

Clear subject, apology, reason, new date, polite close — then proofread.

"How do you make sure your writing is accurate?"

Short sentences, a checklist of your usual errors, reading aloud and tools.

"Tell us about your last project." (spoken)

Use past simple for finished work and present perfect for results.

"What's the difference between 'fewer' and 'less'?"

Fewer for countable nouns, less for uncountable.

• "Is there a style guide?" — standards.
• "Who reviews written work?" — feedback.
• "What writing do I do most?" — focus.
• "Which tools are used?" — support.

• Emails — every message.
• Chats — quick but visible.
• Reports — read by managers.
• Tickets — clear problem descriptions.
• Presentations — slide text.
• Speech — tenses in meetings.

"When do you use 'since' and 'for'?"

Since with a point in time (since 2023); for with a duration (for three years).

"What's a run-on sentence?"

Two or more sentences joined without proper punctuation or connectors.

Table: A first-90-days plan (editorial guidance)

Use team templates in the first month. Ask a colleague to mark patterns in your writing. By the third month, produce reports that need little editing.

Grammar checkers and AI assistants now fix most surface errors instantly. That raises expectations: careless mistakes look worse because they're easy to avoid. But tools can change meaning or tone, so you still need enough grammar to judge their suggestions.

Wait before rereading. Read aloud slowly. Check one thing at a time — names, numbers, then tenses. Use a grammar tool as a second check, not the first.

Ask: is this one of many (a/an), a specific one we both know (the), or a general idea (no article)? Practise with your own sentences rather than rules alone.

Keep one idea per sentence. Use full stops more often. Connect related ideas with "and", "but" or "because", not commas alone.

Read well-edited writing in your field — industry newsletters, company blogs, documentation. Notice how writers use tenses and articles. Copy useful sentence patterns into a notebook and reuse them in your own emails. Grammar learned in context sticks better than rules memorised alone.

"Grammar tools make grammar irrelevant." You still need to judge them.

"Complex sentences sound smarter." Simple sentences are clearer.

"Spoken grammar doesn't matter." Interviewers notice it.

Many learners overuse or avoid the present perfect. Use it for experience without a specific time ("I have worked with US clients"), for recent results that matter now ("I've finished the report") and with "since" or "for" for situations that continue ("I've led the team since 2024"). Use the past simple when you mention a finished time ("I finished the report yesterday"). On CVs and in interviews, this difference makes your English sound accurate and natural.

Keep the subject and verb close together and near the start of the sentence. Use one main idea per sentence. Prefer active voice: "The team approved the budget" rather than "The budget was approved by the team". Avoid stacking several clauses with commas. Short, active sentences reduce grammar errors and are easier for international readers to understand.

Spoken errors matter in interviews and calls. Record yourself describing your last project and listen for repeated mistakes, often with tenses, articles or third-person 's'. Choose one error to fix each week and practise correct sentences aloud until they feel natural. Slow down slightly when speaking; many spoken errors come from rushing rather than not knowing the rule.

Some common work words are uncountable in English: information, advice, feedback, equipment, software and furniture. Say "some information" or "a piece of advice", not "an information" or "advices". Learn the uncountable words used most in your field and check new nouns in a dictionary.

Use past tense for previous roles and present tense for your current role. Start bullet points with action verbs, keep them parallel in form and remove personal pronouns. Read it aloud once, line by line.

• Errors on the CV.
