Surface Forms

nonessential positive

Morphology

nonessential = essential (transparent) = non + essential

Standard negative prefix 'non-' attaches to the adjective 'essential' to give the straightforward opposite meaning.

Etymology

Nonessential is formed from non- ('not') and essential ('most important' or 'basic'). So, when something is nonessential, it is 'not necessary' and can often be left out.
