The ability of a system or product to be improved or enhanced by adding or changing parts.
The upgradability of the software allows users to add new features easily.
Upgradability → It is formed from "upgrade" (from the prefix "up-" meaning higher or above, and "grade" from Latin "gradus" meaning step or degree) and the suffix "-ability" (meaning the quality of being able to). The word "upgradability" refers to the quality of being able to be upgraded or improved to a higher standard.
Think of 'up' meaning higher and 'grade' as a step or level — this helps you remember that 'upgradability' is about the ability to move to a higher level.
