IPA: /rɪˈsɜːrʧəbl/
KK: /rɪˈsɜːrʧəbl/
Something that can be studied or investigated in detail to gain more information or knowledge.
The topic is researchable, allowing scholars to explore it further.
Researchable → It is formed from "re-" (meaning again) and "search" (from Old French *cerchier*, meaning to seek or look for) and "-able" (meaning capable of). The word "researchable" means capable of being searched or investigated again.
Think of 'searching again' ('re-') for information that can be 'looked for' ('search') — that's what researchable means.
