  :Disagree. The terminology used in heraldry and vexillogy are predominantly French/Old French in origin and were in use for centuries before heraldic devices and their associated flags found their way north to the Gaelic speaking areas of Scotland. The term Saltire is not exclusive to the flag of Scotland, but applies to any X-shaped design which appears in heraldic devices (coats of arms etc.) and flags. If anything, Sròl Tìr itself probably stems from the Old French saultoir. In any event, for the Gaelic to be mentioned at all a WP:RS supporting this assertion would have to be found, otherwise...
