Morphology

untoughened = toughened (transparent) = un + tough + en + ed

The negative prefix 'un-' attaches to the past-participle/adjective 'toughened' to yield the straightforward meaning 'not made tough'.

Etymology

Untoughened is made of un- ('not') and toughen (from tough, meaning 'strong' or 'hard'), so it literally means 'not made strong' or 'not hardened'. That's why we use it for muscles, skin, or glass that have not become tough and can be more easily hurt or broken.
