IPA: /dɪˈbɪləti/
KK: /dɪˈbɪləti/
The condition of being weak or lacking strength, often due to illness or age.
After the long illness, she experienced a significant debility that made it hard for her to walk.
Debility is formed from "de-" (meaning down or away) and "bilis" (from Latin, meaning able). The word describes a state of being weakened or unable, hence referring to physical or mental weakness.
Think of 'down' ('de-') leading to a state of being 'unable' ('bilis') — that's why debility means a state of weakness.
