to george, with respect. sassenach just means saxon. there is no x in gaelic, at least not scots. the lowland scots do use it as an insult but highlanders mean nothing more than saxon. it refers to all southern germanics traditionally but specificcaly the english, the norse , although germanic were the laughlannach, or inmodern idiom, luaghlanders.and several other names. they were fully intermarried with highlanders by the time of glemcoe, so although they were barbaric they were part of the culture

peole try to make a big deal of what an insult it was, but in traditional highland culture , where men recited their lineage before battle, an insult that your grandfather ran from killiekrankie or such was the real insult, especially if true.
