The waiter brings dessert after a meal. A desert may be many miles from the nearest restaurant. One extra s changes the word completely.
Open lessonDo or make: common English collocations in context

Open lessonDouble negatives: when English negatives change the meaning
‘I didn’t see nobody’ and ‘I didn’t see anybody’ may sound similar in a quick conversation, but standard written English treats them differently. The extra negative can change the grammar or make the sentence hard to interpret.
Open lessonEach or every: individuals and the whole group
Each draws attention to separate people or things. Every means all members are included, with none left out.
Open lessonEither or neither: choose between two possibilities
Either means one or the other of two things, while neither means not the first one and not the second one.

Open lessonMyself and me: reflexive pronouns without common mistakes
You might hear Please contact myself in a meeting or read Sam and myself in an email. The speaker may be trying to sound formal, but myself has a specific job. Once you check who does the action and who receives it, the choice becomes much easier.
Open lessonOf and off: spelling, sound, and meaning
The words of and off differ by one letter, but they do different jobs in a sentence. The extra f changes both the sound and the meaning.
Open lessonPlain or plane: meaning and spelling in context
The instructions were plain, so we boarded the plane at the correct gate. The words sound the same, but their spellings point to different meanings.
Open lessonPrinciple or principal: rules, people, and spelling

Open lessonSince or for: talking about time correctly
Two short words answer different time questions. Since tells your listener when something began. For tells them how long it has lasted.
Open lessonSo or such: choose the right pattern for emphasis
The two sentences carry the same feeling, but their grammar changes: The film was so moving. It was such a moving film. Look at the word that follows the emphasis word before you choose so or such.

Open lessonTill or until: meaning, form, and sentence position
Your train leaves at six, and you have to stay at work until five. One short word tells us where that waiting period ends.
Open lessonTire or tyre: choose the American or British spelling
A shop in London may advertise new tyres, while a shop in Chicago advertises new tires. The objects are the same. The spelling changes with the variety of English.
Open lessonWhen or if: choosing the condition word
A friend says, "When I see Nora, I'll give her your message." The speaker expects to see Nora. Change when to if, and the sentence means that seeing Nora is uncertain.
Open lesson
The short answer
Match your verb to the subject and keep verbs simple after did. Small word choices change your whole sentence.
She lives in London and she didn't miss her train today.
Why it works: Use the -s form after the singular subject she and keep miss simple after didn't.

Did you see the new office yesterday?
Keep the main verb in its base form after did.
Not this:
Did you sawthe new office yesterday? What changes: Using two past forms together sounds wrong to native ears. -

They're waiting near their car over there.
Each word has a different job even though they sound the same.

Read the full guide
Try the listening exerciseYou chat with a coworker by the coffee machine. You want to share a quick story, but pause on a verb ending. Clear rules help you choose the right form without worry.
Add -s in the present simple
The problem: I know the rule but I still forget the -s on verbs when I talk about my friend or boss in the present simple.
Use -s or -es after he, she, it, or a singular noun. Use the base form after I, you, we, and they.
-
Not this:
My manager work in the city centre.Say: My manager works in the city centre.
Manager is a singular noun, so use works in this daily habit.
Your turn
Choose the correct sentence to describe your manager's routine.
Answer: My manager starts work at eight.
Show the answer
Answer: My manager starts work at eight.
Use starts because manager is a singular noun in a present simple routine.
Keep base verbs after did
The problem: I say 'Did you went?' because I try to put both the helping word and the action word in the past.
You ask a friend about yesterday. The helper word did already carries the past time. Your action word stays in its simple base form.
-
Not this:
Did you went to the meeting this morning?Say: Did you go to the meeting this morning?
Did already shows the past, so use go, not went.
Your turn
Which question is correct for a past project?
Answer: Did you finish the report yesterday?
Show the answer
Answer: Did you finish the report yesterday?
The helping word did shows past time, so finish stays in its base form.
Tell there their they're apart
The problem: The words 'their', 'there', and 'they're' sound the same when people talk fast, so I mix up which spelling and form to use.
Three small words sound identical when you hear them in fast speech. Look at who owns what or where things sit. Each spelling belongs to a different job.
| Spelling | Meaning | Example |
|---|---|---|
| there | A place or location | The keys are over there. |
| their | Belonging to them | They brought their laptop. |
| they're | Short for they are | They're ready for lunch. |
Your turn
Type there, their, or they're to complete the travel sentence.
Answer: The guests left their bags in the hotel lobby.
Show the answer
Answer: their
Use their because it shows that the bags belong to the guests.
Use to with listen and explain
The problem: I say 'explain me the rule' or 'listen music' because my first language does not use 'to' there.
Listen needs to before the sound or thing you listen to. Explain can take a thing directly: explain the plan. Use to before the person who receives it: explain the plan to me.
-
Not this:
Can you explain me the new schedule?Say: Can you explain the new schedule to me?
Explain takes the schedule directly. Use to before the person receiving the explanation.
-
I always listen to the news on my drive home.
Why it works: Listen connects to the news with to.
-
She will explain the plan to our team tomorrow.
Why it works: Explain takes the plan as its object. Use to before the people who receive the explanation.

At a dinner party with new friends
Answer: I didn't buy tickets yet, but my sister wants to go on Sunday.
Show the answer

Save my progressQuestions about "Common English mistakes: choose the form you mean"
When does a present simple verb need an -s ending?
Most present simple verbs take -s or -es with he, she, it, or a singular noun such as my cousin. Use the base form with I and you, even when each refers to one person. After does or doesn't, the main verb also stays in its base form.
I teach art.
My cousin teaches art.
Why does the verb stay in its base form after did?
Did marks the past in these questions and negatives. Use the base form after did or didn't, including with irregular verbs. In a positive sentence without did, the main verb takes its past form. Check which verb is carrying the past meaning before adding an ending.
Did Mina find her glasses?
Mina didn't find her glasses.
How do I choose between their, there, and they're?
Use their to show that something belongs or relates to someone. They're is the short form of they are. There can point to a place or introduce something that exists. Try replacing they're with they are, then check what the sentence means.
Their garden has a lemon tree.
They're planting flowers.
There's a small bench by the gate.
Do I always need to after listen?
Use listen to when you name the person or sound you are paying attention to. If you do not name that object, listen can stand without to. This is why both listen carefully and listen to the instructions are useful patterns.
Please listen to the final instruction.
He closed the book and listened.
Why do I say explain it to me?
Put the thing you are explaining directly after explain. If you also name the person receiving the explanation, introduce that person with to. You can leave the person out when the context is clear; explain does not always need a phrase with to.
The teacher explained the puzzle.
The teacher explained the puzzle to me.
