The KJV “an other” is contracted which is the same as another. The context in the book of Galatian is “faith + works”. The gospel message is to be receive by faith, the problem is that Judaizers have introduce “an other” gospel which is not another but a mixture, corrupting the true gospel by adding a work based salvation or the Law on the already established faith of the Galatian believer's and that is the problem. It is not "different gospel" in the sense that it does not involved faith so that this will introduce another one of different kind i.e. salvation is by Law or works only, but rather it is Grace + Law that was introduce to the Galatian believers.
