More conditions (salvo si, con que, tanto si… como si)

Salvo si and excepto si + indicative

You know salvo que + subjunctive for unless. Put si in place of que and the verb goes into the indicative, as it always does after si in the present: salvo si llueve, excepto si hay tráfico. The meaning stays close: except if.

Salvo si llueva is wrong: after si, never the present subjunctive.

Con que + subjunctive: that's all it takes

Con que + subjunctive sets a minimum: if just this happens, it is enough. The rest of the sentence often says so, with me basta, es suficiente or no hay problema.

Mientras + subjunctive also means as long as, but it sets a condition that must keep holding; con que stresses that one small thing is all you ask.

Write it as two words: conque, in one word, means so.

Tanto si … como si: either way

Tanto si A como si B says the result is the same whichever happens, like English whether … or. Both halves take the indicative (never the present subjunctive), and como si no stands for the negative half.

Here como si pairs with tanto; it is not the como si of as if, which takes the subjunctive.
