Questions & Answers about Para templar la espada, debes enfriarla en aceite.
Why is para used here instead of por?
I learned that templar means "to warm up". Why does it translate to "to temper" here?
You're right! Templar often means to take the chill off something or warm it slightly (like agua templada). However, in metallurgy or cooking, it specifically means "to temper"—the process of heating and then cooling a material to change its hardness. The context of a sword (espada) makes this specific meaning clear.
How could I add a warning to this sentence using no sea que (lest / just in case)?
You could say: Para templar la espada, debes enfriarla en aceite, no sea que se rompa (To temper the sword, you must cool it in oil, lest it break). Remember that precautionary phrases like no sea que and no vaya a ser que are always followed by the subjunctive—in this case, se rompa.
Since debes is conjugated, could I put the la before it and say la debes enfriar?
