When I first started studying for the TOEIC, I thought learning a large number of words was enough. But after working through practice tests, I realized that quite a few of my wrong answers came from confusing words that looked or felt very similar. Some pairs differ by just one letter, some have meanings that are close but not identical, and others look familiar but are used in completely different contexts.
The hardest part is that TOEIC doesn't just test individual word meanings. Many questions also test collocations — which words naturally go together. I could understand a sentence reasonably well and still choose the wrong answer simply because I wasn't familiar with how certain words combine.
For example, I often got tripped up on words related to office work, orders, appointments, and costs. These topics come up constantly in TOEIC, so confusing even one word can cost you points immediately.
The Most Easily Confused TOEIC Word Pairs
1) accept and except
These two words look very similar, but their meanings are completely different.
accept = to agree to receive or take something
except = excluding; other than
I remember this pair by focusing on the ac- in accept — as in "accept a gift." For except, I think of it as "excluding" something from a group.
The manager accepted the proposal.
Everyone except Mark attended the meeting.
2) affect and effect
Keep reading
This is one of the pairs I got wrong most often in the beginning.
affect = to have an impact on something (verb)
effect = a result or outcome (noun)
My trick: Affect is an Action — it's the verb that describes something acting on something else. Effect is the end result of that action.
The delay affected our schedule.
The new policy had a positive effect on sales.
3) salary and wage
I used to treat these as interchangeable since both mean "pay." It wasn't until later that I noticed the difference in usage.
salary = fixed pay, typically paid monthly or annually
wage = pay based on hours, days, or weeks worked
When a sentence is about an office employee, I almost always see salary. For seasonal or hourly work, wage is the typical choice.
Her salary was increased after the annual review.
The company pays hourly wages to part-time workers.
4) borrow and lend
I used to confuse this pair because both involve the idea of "lending/borrowing." After spending time on Parts 2 and 7, I started separating them like this:
borrow = to take something from someone else for temporary use
lend = to give something to someone else for temporary use
I remember it by thinking about direction: if I'm receiving something, that's borrow; if I'm giving something, that's lend.
Can I borrow your pen?
Could you lend me your pen?
5) meet and meet with
These aren't completely different in meaning, but I find them very easy to misuse in TOEIC.
meet = to see or encounter someone
meet with = to have a discussion or formal meeting with someone
Meet with appears frequently in business emails. I used to skim past it and assume it just meant "see someone," but it actually carries a slightly more formal, purposeful tone.
I need to meet with the client this afternoon.
She met her friend after work.
6) resume and summarize
I find resume particularly tricky because it functions as both a noun and a verb.
resume = to continue (verb)
summarize = to give a brief account of the main points
In TOEIC, resume can also mean a CV when used as a noun, but I prioritize learning the verb meaning first since it appears more often in workplace contexts.
Let's resume the discussion after lunch.
Please summarize the report in two paragraphs.
7) invoice and receipt
This pair comes up very frequently in TOEIC Part 7.
invoice = a document requesting payment (sent before payment)
receipt = a document confirming that payment has been made
My simple rule: an invoice is sent to ask for money; a receipt is issued after money has been paid.
Please send the invoice to the accounting department.
Keep the receipt in case you need a refund.
8) schedule and agenda
I used to think both words just meant "schedule," but TOEIC uses them quite differently.
schedule = a timetable or plan showing when things will happen
agenda = a list of items to be discussed at a meeting
I once chose the wrong word because I saw "meeting" in the sentence and automatically thought of schedule. But if the sentence is about the specific topics to be covered in a meeting, agenda is the right word.
The train schedule was updated this morning.
The agenda includes budget approval and hiring plans.
How I Remember Them and Make Fewer Mistakes
1) I learn phrases, not isolated words
This approach works far better for me than learning single words. Instead of just noting invoice = a billing document, I write down:
send an invoice
pay the invoice
keep the receipt
Learning in phrases gives me both the context and the natural word combinations. When I'm doing a practice test, I don't just see a lone word — I see the whole picture around it.
2) I write one short English sentence for each word pair
Whenever I encounter a confusing pair, I write one very short, TOEIC-style sentence for each word. For example:
The manager accepted the offer.
The policy affected the budget.
Writing my own sentences helps me retain the words far longer than simply reading a definition.
3) I create an "anchor" to tell them apart
For each word pair, I attach a simple image or association.
borrow = I'm taking something from someone
lend = I'm giving something to someone
salary = monthly pay
wage = hourly pay
invoice = a request for payment
receipt = proof that payment was made
The simpler the anchor, the faster I remember it.
4) I review using flashcards based on my own mistakes
I don't review all vocabulary evenly. I focus specifically on words I've gotten wrong before. This is the habit that has helped me improve the most.
If I get accept/except wrong today, I add it to my review list for three days later, then again a week later. Using this method, I've found that repeated mistakes drop off significantly over time.
A Few Mistakes I've Made
I once chose effect instead of affect in a reading comprehension question simply because it looked more familiar. I also confused schedule with agenda in a business email section, which threw off my understanding of the entire sentence.
What I learned from this is: reading TOEIC questions with only a rough sense of a word's meaning isn't enough. In many questions, getting just one word wrong completely changes the meaning.
I also made the mistake of trying to study too many word pairs at once, which left everything jumbled in my head. I eventually switched to learning fewer pairs at a time but learning them thoroughly, then reviewing them repeatedly. That approach suits me much better.
Conclusion
If I had to sum up this entire post in one sentence, it would be: with TOEIC, easily confused words aren't the real problem — not having the right study method is.
I no longer try to learn as many words as possible each day. Instead, I focus on the most commonly confused pairs, learn them in phrases, write short example sentences, and review based on my own mistakes. It's not a flashy method, but for me, it works far better than anything else I've tried.
If you're preparing for the TOEIC and keep losing points on vocabulary, I'd suggest starting with just 5–10 of the most confusing pairs. Learn slowly, but learn solidly. That's exactly what I'm still doing myself.
Frequently asked questions
Làm sao để nhớ các cặp từ TOEIC dễ nhầm lâu hơn?
Mình thấy hiệu quả nhất là học theo cụm từ, tự đặt câu ngắn và ôn lại đúng những từ mình từng sai thay vì học dàn trải.
Có nên học nghĩa từng từ riêng lẻ không?
Có, nhưng mình không dừng ở nghĩa lẻ. Mình thường học thêm cách dùng, collocation và ngữ cảnh vì TOEIC hay kiểm tra phần này.
Từ dễ nhầm có hay xuất hiện trong TOEIC không?
Có. Đặc biệt trong Part 5 và Part 7, các từ gần nghĩa hoặc nhìn giống nhau xuất hiện khá thường vì đề kiểm tra độ chính xác.
Mình nên ôn bao nhiêu cặp từ mỗi ngày?
Mình thường chọn ít thôi, khoảng 5 đến 10 cặp, nhưng ôn kỹ và lặp lại nhiều lần để tránh nhớ lẫn.
