Dependability → It is formed from "de-" (meaning down from or away) and "pendere" (meaning to hang). The word "dependability" refers to the quality of being able to rely on something or someone, as if it hangs down from a source of trust.
Think of something that 'hangs down' ('pendere') from a source of trust ('de-') — that's why dependability means you can rely on it.
