Spanish

I had an entertaining episode yesterday when I was helping a lady with her Spanish homework (Level A2) despite never having learnt a word of Spanish; apparently a knowledge of French, English, a smattering of Italian, and an acquaintance with Hornblower and the Peninsular War are enough to get you a long way :-D
What I don't have, of course, is any knowledge of the grammatical structures, but since I know grammar *in theory* it was easy enough to identify what the questions in the course book were designed to test (e.g. masculine/feminine/plural endings)...

Interestingly, the Spanish word for 'oil' looks as if it ought to mean 'vinegar': aceite
