"They do not speak Spanish in Brazil!"
Translation:De snakker ikke spansk i Brasil!
Hehe, yes, and it gets even more fun with sentences like "Jeg har ei ei mor. Har du ei?". ;)
There is 'ei' the adverb, 'ei' the indefinite article, 'ei' the number, and 'ei' the pronoun. Of course you can avoid using all of these by substituting the the first one with 'ikke' and all the latter with 'en' (if you opt for using the masculine versions of the nouns), but even so you need to be able to recognize them in speech and writing.
