Etymology

the word 'mutable' has a direct lineage from latin, entering english in the late 14th century via the old french 'mutable'. its core component, the latin root 'mut-', meaning 'to change', is a prolific source for english vocabulary, seen in words like 'mutate', 'commute', and 'mutual'. the suffix '-able' attaches to this verbal root to create an adjective describing the quality of being susceptible to change. thus, the literal construction 'capable of change' elegantly captures the modern abstract meanings, from describing fickle weather to the technical property of modifiable data in programming.

Analysis

Structure: mut (change) + able (capable of) 'mut' originates from the latin verb 'mutare', meaning 'to change'. 'able' is a suffix of english origin (from latin '-abilis') used to form adjectives meaning 'capable of, fit for, or worthy of'.
