i thought it wasn’t too far of a leap myself (both start with s, end with nasal), and being able to understand the rest of the sentence was also helpful
you did note the pronunciations in there though, and to be fair, i’d probably struggle more with understanding the portuguese if it was spoken out loud instead
It wouldn’t help much in this case as ES “sin” /sin/ and PT “sem” /sẽ/ already look quite different from each other.
