   Word Origin early 17th century: from Latin evolutio(n-) ‘unrolling’, from the verb evolvere (see evolve). Early senses related to movement, first recorded in describing a ‘wheeling’ manoeuvre in the realignment of troops or ships. Current senses stem from a notion of ‘opening out’, giving rise to the sense ‘development’.
