I just reduced the longer version of the Amharic translation for the word 'and'. The other challenge I see is how to use punctuations, as there are two full stops in the original string, I figured there should be two here too. If the size of text is of the matter, they can be removed, as it would have no change in meaning.

The word 'invalid' is translated as 'incorrect' or 'wrong' for the Amharic translation. There is no common translation for the word that doesn't sound obtrusive. So I decided to stick with it.
