I've argued that there are three main strands to learning a new language - grammar, which teaches us how the language puts words together to make sense, vocabulary, which gives us the words, and usage, which tunes us in to how speakers of the language use the first two. The Guardian has an excellent selection of proverbs, here, which illustrate the value of the third part. The French do not, as far as I know, whip cats, and the Spanish do not give people pumpkins. Neither do I know how far a German cat can jump. Good fun, all the same. Pictures by Marcus Oakley and Matt Lindley for the website Hotel Club.
