IPA: /ˈrɛkənˌdaɪt/
KK: /rɪˈkɒnˌdaɪt/
Something that is not easily understood or is hidden from common knowledge.
The professor's lecture on quantum physics was filled with recondite concepts that confused most of the students.
Recondite → It is formed from "re-" (meaning again) and "condere" (meaning to put together or store). The word describes knowledge that is stored away or not easily accessible, hence, obscure or little known.
Think of knowledge that is 'put away' ('condere') and 'again' ('re-') — this helps you remember that 'recondite' refers to something that is obscure or not easily understood.
