Questions & Answers about El precio fijo no cambia; en cambio, el precio indexado sí.

Why is sí at the end of the sentence?

Here sí is being used to stand in for the omitted verb phrase, a lot like English does in the indexed price does.

So:

• El precio fijo no cambia = the fixed price does not change
• el precio indexado sí = the indexed price does

It avoids repeating cambia. A fuller version would be:

• El precio fijo no cambia; en cambio, el precio indexado sí cambia.

Both are correct, but the shorter version sounds more natural because Spanish often leaves out repeated material when it is obvious.

Why does sí have an accent mark?

Because sí with an accent is the affirmative word meaning yes or indeed / does in this kind of contrast.

Without the accent, si usually means if.

So these are different words:

• sí = yes / indeed / does
• si = if

In your sentence, it must be sí because it is affirming the contrast: the fixed price does not change, but the indexed price does.

Why use en cambio instead of just pero?
