Strict conditional linkers (siempre y cuando)

Setting Strict Conditions

When negotiating or setting firm boundaries, you often need to express that an agreement depends on a specific requirement. In Spanish, use conditional linkers.

The most common phrases are:

  • siempre que (as long as)
  • a condición de que (on the condition that)

Because these phrases set a condition for the future, they are always followed by the subjunctive mood.

The director will help you as long as you assume the risk.
La directora te ayudará siempre que asumas el riesgo.
They will accept the deal on the condition that we pay the advance.
Ellas aceptarán el trato a condición de que abonemos el anticipo.

Stronger Requirements

For a more formal or strict tone, siempre y cuando (provided that) and con tal de que (so long as) clearly define absolute boundaries.

The contract is valid provided that you pay every month.
El contrato está vigente siempre y cuando abones cada mes.
The notary will come so long as the document is valid.
El notario vendrá con tal de que el documento esté vigente.

These conditional linkers are extremely common in professional contexts, such as when discussing contracts with a notary, setting up a guarantee, or negotiating compensation.

The notary will sign the guarantee as long as there are no problems.
La notaria firmará la garantía siempre que no haya problemas.
He won't take long to sign provided that you assume the cost.
Él no tardará en firmar siempre y cuando asumas el coste.
We won't say anything so long as you pay the compensation.
No diremos nada con tal de que paguéis la indemnización.
