IPA: /rɪˈfɛrəbəl/
KK: /rɪˈfɜrəbəl/
Able to be mentioned or pointed to as a source of information or reference.
The data in the report is referable to the original study conducted last year.
Referable → It is formed from "re-" (meaning again) and "ferre" (meaning to carry or bring). The word "referable" means something that can be brought back or referred to again.
Think of something that can be 'brought back' ('ferre') for consideration 'again' ('re-') — that's why referable means it can be referred to.
