IPA: /ˌriːprəˈɡræməbəl/
KK: /riˈprɒɡrəˌmɛbəl/
Able to have its programming changed or updated with new instructions or software.
The new smartphone is reprogrammable, allowing users to install different operating systems.
Reprogrammable → It is formed from "re-" (meaning again) and "program" (from Greek "programma", meaning a written public notice or a plan) and "-able" (meaning capable of). The word "reprogrammable" means capable of being programmed again or modified.
Think of 'again' ('re-') and a 'plan' ('program') that can be changed — that's why reprogrammable means something that can be programmed again.
