In swedish there are two synonyms for English word "fast": 1. snabb 2. rask I don't understand the difference of those adjectives. A lot i see phrase "i rask takt", which means that something has good (not slow) tempo. But also the "snabb" means a higher tempo. Can you explain, when i need to use Snabb and when Rask? I only have a beginner level in Swedish, so i cannot formulate my question text in Swedish here yet.
