Change means altering or making something different in a particular way, or transforming it altogether. It can also mean giving something a new position, direction, or replacing one thing for another.[1][3]
The word "change" comes from Middle English, derived from Anglo-French "changer," which in turn comes from Latin "cambiare," meaning "to exchange." It may have connections to Old Irish "camm," meaning "crooked".[3]
“change, alter, vary, modify mean to make or become different. change implies making either an essential difference often amounting to a loss of original identity or a substitution of one thing for another. alter implies a difference in some particular respect without suggesting loss of identity. vary stresses a breaking away from sameness, duplication, or exact repetition. modify suggests a difference that limits, restricts, or adapts to a new purpose.”
