no

The word "no" is the direct equivalent of "no" in English, serving as the primary way to express negation, refusal, or disagreement. It is a simple, versatile particle used to answer questions negatively or to negate an entire clause. In Swedish, "no" is used in the exact same contexts as its English counterpart. You might use it to decline an offer, contradict a statement, or express a lack of something. It is neutral in register, making it perfectly appropriate for both everyday casual conversation and professional settings.
