Warm-up

Let's see what you already do naturally — don't worry about the grammar words, just have a go.

Read these two messages. They say exactly the same thing.

Message 1: "Went to the market. Bought vegetables. Forgot the eggs."

Message 2: "I went to the market and bought vegetables, but I forgot the eggs."

Which one sounds more like something a person would actually say out loud? Say your idea before you check.

Check your idea CLICK
Message 2 — because it uses joining words (and, but) to show HOW the ideas connect. "And" adds one thing to another; "but" shows the surprise (shopping done, except for one thing). Short sentence after short sentence sounds like a list, not like speech. Today you'll build sentences the second way.

Complete the sentence the way you'd say it to a friend:

"My alarm didn't go off, I was late for work."

SPEAK

Have a go out loud: describe your morning today in one or two joined sentences — not a list of short ones.

Today: turn short, choppy sentences into one clear sentence — joining ideas with and, but, so or or; adding reasons, contrasts, times and conditions with because, although, when, if, after or before; and adding extra detail about people or things with who, which or that — so you can speak and write more naturally, without sentences that just stop and start.

Joining Two Ideas: "and / but / so / or"

For two complete ideas that belong together — add, contrast, show a result, or offer a choice.

Spot the pattern

Three everyday sentences:

Look at what's before and after the comma in each one. Say what you notice before you check.

Check the pattern CLICK
Before the comma: a full sentence that could stand alone. After the joining word: another full sentence that could also stand alone. Comma + and / but / so / or joins two complete sentences into one — each half keeps its own subject and verb.
sentence 1 , and / but / so / or sentence 2

and adds one thing to another · but shows a contrast · so gives a result · or offers a choice.

"I finished the report early. I sent it straight away."
→
"I finished the report early, and I sent it straight away."

Your turn

Join each pair into one sentence. Type only the missing word.

1. My sister lives in Berlin. She visits us every summer.

"My sister lives in Berlin, she visits us every summer."

2. The flat is small. It's got a lovely view.

"The flat is small, it's got a lovely view."

3. The heating broke down last night. We had to wear coats indoors.

"The heating broke down last night, we had to wear coats indoors."

SPEAK

Say two things about your week, joined with and, but or so — not as two separate sentences.

Giving Reasons & Conditions

because, although, when, if, after, before — one idea depends on, contrasts with, or happens around another.

Spot the pattern

These joining words can go in the middle of the sentence or right at the start. When one starts the sentence, what punctuation follows the first part? Say it before you check.

Check the pattern CLICK
A comma. "Although it was raining, we walked..." — clause first, comma, then the rest. But in the middle, no comma: "I was late because the bus didn't come." Same meaning, same joining word, different position.
sentence + because / although / when / if / after / before + clause
Because / Although / When / If / After / Before + clause , sentence

because = reason · although = contrast · when = a moment in time · if = something that might happen · after / before = order in time.

Your turn

1. I couldn't answer the phone. I was in a meeting.

"I couldn't answer the phone I was in a meeting."

2. He had the right experience. He didn't get the job.

he had the right experience, he didn't get the job."

3. You might be running late tonight. Send me a text.

"Text me you're running late tonight."

SPEAK

Say three things about your day: one with because (a reason), one with although (a contrast), and one with if (something that might happen).

Adding Extra Information: "who / which / that"

Instead of two separate sentences about the same person or thing, add the extra detail inside one sentence.

Spot the pattern

Which word describes a person, and which describes a thing? Say it before you check.

Check the pattern CLICK
who = people. which = things. that = people or things — very common in speech for both, especially when the detail isn't extra, it's essential to knowing which one you mean (like the jacket).
who = people
which = things
that = people or things (informal, everyday)
"I have a friend. She speaks four languages."
→
"I have a friend who speaks four languages."

Your turn

1. My colleague speaks Italian. She's helping me plan my trip.

"My colleague, speaks Italian, is helping me plan my trip."

2. The bus was late again. It goes to the station.

"The bus goes to the station was late again."

3. The man answered the phone. He works at the garage.

"The man answered the phone works at the garage."

SPEAK

Describe two people you know using who, and one thing you own using which or that.

Your Turn to Talk

Time to use all three kinds of joining in one real story.

The situation

Think of something that happened to you recently — a small piece of news, a plan, or a mix-up. (If nothing comes to mind, invent one.)

Tell the story out loud for one minute. Try to include:

01:00

Now put it in writing

Write a short message (3–5 sentences) about the same story. Use all three kinds of joining from today — the checker will tell you which ones it finds.

Mix It Up

Real sentences don't come labelled with the grammar point. Fix these, then choose the word that fits.

Fix the run-on sentences

Each one below is a comma splice — two full sentences stuck together with just a comma, no joining word. Rewrite each as one clear sentence, keeping the two ideas in the same order.

1. "The kettle broke, I had to buy a new one."

2. "I wanted to go for a walk, it started raining."

3. "I was worried, my flight was delayed by six hours."

4. "I met a woman, she used to be a professional dancer."

Which word fits?

5. "It was late, ___ I decided to stay another hour."

6. "___ the traffic was terrible, we arrived on time."

7. "The restaurant ___ we went to last night was fully booked tonight."

SPEAK

One-minute challenge: tell me about a mix-up or a piece of news from your week. Use at least one and/but/so, one because/although/when/if, and one who/which/that — mixed together, your choice of order.

What Do You Remember?

First, from earlier lessons

1. The simplest joining word — the one you learned right at the start. Complete it: "I like pizza pasta."

2. Say it out loud: what's the difference between a comma splice and a properly joined sentence? Give one example of each.

Compare with a possible answer CLICK
One possible answer: a comma splice is two full sentences stuck together with only a comma — "It was cold, I put on a coat." A properly joined sentence adds a joining word to show HOW the ideas connect — "It was cold, so I put on a coat." The comma alone doesn't tell you if it's a reason, a contrast, or just two facts; the joining word does.

Now, today's grammar — fresh sentences, no looking back

3. My laptop crashed twice today. I still finished the report.

"My laptop crashed twice today, I still finished the report."

4. Call the dentist. Your tooth still hurts.

"Call the dentist your tooth still hurts."

5. The email needs a reply. It's from your landlord.

"The email is from your landlord needs a reply."

Think back

Which kind of joining word did you find hardest today — and/but/so/or, because/although/when/if, or who/which/that? Say why, out loud.

Can you now...?

At the start we said: join short sentences into one clear one. Tick what's true:

Anything you didn't tick — go back to that tab and try the exercises once more. They'll still check your answers.
