Not so if you know German, but the reading is slower as normal. German words are often very long, but only because it is a compound word, which in other lenguages need a whole sentence to say the same. The advantage is that it is very easy to invent new words in German which everybody understand, but this is also used often used in legal jargon in an absurd and not needed way. German is a very flexible language with not so much grammatic, the most difficult are the articles. A very precise and uniform pronunciation of the letters in the alphabet used in a word (same as in Spanish), not so in English or French, where letters have different phonetics in different words.
