Questions & Answers about Minun täytyy juosta, jotta syke nousee.
Why do we use jotta here instead of että?
Jotta specifically expresses purpose, meaning "so that" or "in order to". Että simply means "that" and usually connects a statement or thought. If you used että, it would sound like "I must run that the heart rate rises," which misses the clear sense of purpose.
Why is it Minun täytyy instead of Minä täytyy?
The verb täytyy expresses necessity ("must" or "have to") and always requires the subject to be in the genitive case. That is why we use minun instead of the nominative minä. Also, täytyy never changes to match the person; it always stays in this third-person singular form.
Why do we use nousee instead of nostaa?
Nousta (here as nousee) means "to rise" or "to go up" by itself, without a direct object. Since the heart rate is rising, this is the correct verb. If you were actively raising something as an object, you would use the verb nostaa (to raise), like in "nostan sykettä" (I raise my heart rate).
Can the jotta clause have a completely different subject than the main sentence?
