Contrast
Which ideas differ or go against what we expect?
Meaning
Contrast links ideas that differ or go against what we would expect. It can set two facts side by side or show that something happens despite an obstacle. Languages may use linking words, word order, or stress, and some have no dedicated contrast marker. Contrast can set whole statements against each other, while Comparison compares things in a chosen quality or amount.
How to spot it
Look for ideas set against each other, especially where one makes the other unexpected.
In your native language
English uses but to join contrasting ideas and although to introduce a fact that makes the other part surprising. With although, the other part normally has no but. In writing, however often begins a separate sentence and is followed by a comma.
The room is small, but it's comfortable.
But links two contrasting facts in one sentence.
Although it was cold, we sat outside.
The cold makes sitting outside unexpected; there is no but in the other part.
The shoes look nice. However, they're too small for me.
However links the new sentence to the previous one and is followed by a comma.
In your learning language
Pero adds a contrasting idea, while sino replaces something denied with an alternative; use sino que when the replacement has its own conjugated verb. Aunque introduces an obstacle that does not prevent the main event. After aunque, ordinary statement forms can present the obstacle as a fact, while the subjunctive (subjuntivo) can leave it open or treat it as irrelevant to the outcome.
El piso es pequeño, pero tiene mucha luz.
The apartment is small, but it gets plenty of light.
No quiero té, sino café.
I don't want tea; I want coffee.
Sino replaces the rejected option with the desired one.
Aunque llueva, saldremos a pasear.
Even if it rains, we'll go for a walk.
Llueva leaves the rain as a possibility that will not change the plan.
Learners whose language uses one word for both a contrast and a correction may use pero where sino is needed. Learners whose language does not change verb forms after a word meaning although may miss the difference between aunque llueve and aunque llueva.
