I translated "I gave some flowers to your mother" as "Yo le di unas flores a tu madre". It was marked wrong and I can't work out why. I've looked at a couple of other websites and I still don't understand what I've got wrong. One site says that the "le" has to be used. The given answer didn't have "le" in it. Even if the "le" is optional, is it actually incorrect to use it, or have I got it all wrong? Thanks.

What are the other words for adios. Like other slangs which are used in other Spanish speaking countries. Like chao. Are there any other words?

Why use the English translation there is or are,  when hay literally means to have? I would rather think of haber means to have in English. Its too confusing to use there is or there are for translating a Spanish verb that actually means to have. Thank you!
