Able to be burdened or loaded with weight or responsibility.
From Middle English 'burden' (a load or duty) plus the suffix '-able' (capable of being). The word reflects how English forms adjectives by adding suffixes to nouns.
Burdenable is a wonderful example of how English builds vocabulary systematically—if something can be burdened, it's burdenable, and the same pattern works for thousands of other words!
