Well, after 74 daily posts I finally slipped up and missed a couple of days posting. Apologies to regular readers wherever you are.
I have come across a couple of interesting Spanish words recently. Today's was 'postre' - a fairly familiar word meaning 'dessert' or 'pudding'. What I hadn't realised until today was that
el postre = desssert/pudding
a la postre = in the end
So changing the gender of the noun from masculine (el) to femenine (la) changes its meaning. I'm sure there are a few other words like this, but I can't think of any off the top of my head so they can wait until a future post.
