Morphology
deleterious = delete (opaque) = deleter + ious
Although the form suggests 'delete' + '-ious', the adjective's meaning 'harmful' cannot be reliably inferred from the modern verb 'delete' and is etymological rather than a productive modern derivation.
Etymology
The word deleterious comes from the Latin root delere, meaning 'to destroy', and it shares that root with the familiar word delete. So something deleterious is harmful or damaging because it acts like it is destroying part of what it touches.
