Morphology

helmet = helm (semi-transparent) = helm + et

The word is historically 'helm' + diminutive '-et' and the form relation is visible, but '-et' is not a productive English suffix and 'helm' is relatively uncommon, so learners may not reliably infer the meaning.

Etymology

The word helmet comes from the old word helm, which meant 'a covering' or 'protection' for the head, and the small ending -et made it a little or specific helm. So a helmet is a head covering made to keep you safe.
