1) term used to describe someone from scotland. (note: not every1 there rolls their R's and says occh I jimmy al the time)
2) a type of dialect. the scottish language was originally a form of gaelic, from when the irish settled in scotland. That language is rapidly going away and so a form of english is more commonly used in scotland.
the collective noun the "scottish" are a group of people who are born in scotland and face many prejudices from narrow-minded idiots.
seriously, wot is with all the other definitions??? they are completely steriotyped, the people should either get a life or at least VISIT SCOTLAND and see for themselves that the scottish arent all whiskey-drinking, sheep-shagging, kilt-wearing, aggresive pigs.
