Morphology

required = require (transparent) = require + ed

A standard adjectival/past-participle formation from the verb 'require'; learners who know 'require' can derive 'required'.

Etymology

Required comes from Latin parts re- ('again') and quaerere ('to ask' or 'to seek'), and the same root is in question and request. So, to require something is like 'asking for it again' or insisting on it, which is why it means 'officially demanded'.
