Nonnasal → It is formed from "non-" (meaning not) and "nasal" (from Latin "nasalis", meaning related to the nose). The word "nonnasal" refers to something that is not related to or does not involve the nose.
Think of 'non-' meaning 'not' and 'nasal' relating to the nose — so nonnasal means something that is not related to the nose.
