The quality or state of being able to be broken down into smaller parts or components.
The decomposability of organic materials is important for composting.
Decomposability → It is formed from "de-" (meaning down or away), "componere" (meaning to put together), and "-ability" (meaning the quality of being able to). The word refers to the quality of being able to be put down or taken apart.
Think of 'putting together' ('componere') and then 'taking it apart' ('de-') — that's what decomposability means.
