I was tempting to answer the same as you ;-) I see you study German as well...Just like in German, the word Gerne modifies the verb a lot and implies a more polite expression in any translation,to express Likes and Dislikes. I think "would you want" is a little ruder than "would you like" if said from a waiter for example. what do you think?
Sorry, I've search in ORDNET.dk the word HAVE and the result points to this: ,,,"have: substantiv, fælleskøn " Betydninger: " afgrænset område med græsplæne, træer, blomster m.m. ofte i tilknytning til et beboelseshus".,,,, I' ve learnt before that the verb "HAR" is fot "to Have". Someone helps??
