When we talk about the concept of weakest, we often refer to something that is likely to fail or break easily. There are several synonyms that can be used to describe the weakest thing or person. For instance, words like feeble, fragile, frail and delicate are often used to suggest something's weakness. Alternatively, vulnerable, powerless and impotent could be used to refer to someone who lacks strength or authority. Apart from that, terms like inferior, inferior quality or inferiority can be used to describe something that's somewhat inadequate or substandard. It's worth noting that the word "weakest" used in the right context can be quite effective in conveying a sense of something vulnerable or fragile.
