Connectors are how two ideas become one sentence instead of two. And, but, so, because, although, while — each one declares a relationship, and choosing the wrong one changes the meaning even when the grammar is perfect. This is also where the commonest written mistake in Indian English lives: "Although it was raining, but we went" uses two connectors for one relationship.
Example 1 of 3
Rebuild the sentence that gives a reason.
Tap words to add or remove them. Drag words into the answer, or use the buttons. Arrow keys move a selected word.
I stayed home because it was raining.
Because introduces the reason for staying home.
Question 1 of 1
Choose an answer, then check why it fits.
This is a check of this example, not an English level assessment.
Build this reference explanation from the reason to the result.
So we arrived by a different road.
We checked another route.
The road was closed.
Drag the cards or use the up/down buttons.
So introduces the result. The middle action explains how the situation changed.
I stayed home because it was raining.
Reason: why I stayed home.
It was raining, so I stayed home.
Result: what happened because of the rain.
It was raining, but we went outside.
Contrast: the second idea differs from what you might expect.
Every one of these is a sentence Indian-English speakers genuinely produce — not a textbook example.
| Commonly said | Correct English |
|---|---|
I am tired but, I will come. | I am tired, but I will come. The comma goes before "but", not after. and / but / or → |
Because it was raining, so we stayed. | Because it was raining, we stayed. Use one or the other, never both. because / so → |
Although he tried, however he failed. | Although he tried, he failed. One contrast word is enough. although / however → |
Neither he came nor he called me. | He neither came nor called. Keep the two halves the same shape. either…or / neither…nor → |
He is rich, yet but he is unhappy. | He is rich, yet he is unhappy. "Yet" already does the job of "but". so / yet / nor → |
While I was going, I met him while. | While I was going, I met him. The connector appears once, at the front of its own half. when / while / before / after → |
I will wait until you will come. | I will wait until you come. After "until" the future is written in the present. until / since / once → |
As soon as he will arrive, call me. | As soon as he arrives, call me. After "as soon as" the future takes the present tense. as soon as / whenever → |
