Morphology

top + secret

The meaning 'highly confidential; classified at the highest level' is directly and transparently derived from combining 'top' (highest, foremost) with 'secret' (confidential). This modifier+adjective composition is cross-linguistically common and follows a straightforward intensifying pattern, so a B1 learner who knows both words will readily infer the MWE meaning.

Etymology

Top secret comes from the practice of marking the most secret papers with the words Top and Secret and keeping them locked away. So, it now means information that is 'very secret' or 'kept only for a few people'.
