Morphology

maintained = maintain (transparent) = maintain + ed

The adjectival sense is formed from the past participle of 'maintain' and denotes something 'kept' or 'continued', which follows directly from the verb meaning.

Etymology

Maintained comes from old parts manu 'hand' and tenere 'to hold', the same root you see in retain. So when a custom or memory is maintained, it is 'held' or kept over time.
