Not causing or relating to significant change or innovation.
The company's approach to technology was considered unrevolutionary, sticking to traditional methods instead of embracing new ideas.
Unrevolutionary → It is formed from "un-" (meaning not) and "revolutionary" (from Latin "revolutio" meaning a turning or change). The word "unrevolutionary" means not characterized by or promoting significant change or upheaval.
Think of 'not' ('un-') being added to 'revolutionary', which refers to significant change. This helps you remember that 'unrevolutionary' means lacking in significant change.
