Like a paradigm?
Yes exactly like paradigm! The roots here mean:
Παρά: next to, adjacent, similar
Δείγμα (related to the verb δείχνω): show, explain, point to
So, if you'd like, you could think of it as 'pointing out something similar to the thing being discussed'.
it looks like ! it makes sense now ...
Sometimes, as with παράδειγμα, the word is identical in form and base meaning (example) to the ancient word.
