gradual

the word 'gradual' originates from the latin 'gradualis', meaning 'of or pertaining to steps'. this derives from 'gradus', meaning 'a step, pace, or degree'. the semantic journey is remarkably direct: the concept of moving by individual steps evolved into the abstract notion of progression by small, incremental stages. the term entered english in the late middle ages, initially with a literal sense related to steps, but its modern meaning describing slow, step-by-step change was firmly established by the 16th century.

Structure: grad (step) + ual (adjective suffix) grad (from latin 'gradus', meaning 'step' or 'degree'); ual (a latin-derived adjective-forming suffix, from '-alis', meaning 'pertaining to').
