Tartan is a thick, woollen, checked material. It was worn hundreds of years ago in the Highlands of Scotland. Each family, (Clan) had their own tartan and Chief. For example, the Grant clan has its own tartan.
The kilt is made of tartan and is the traditional dress of Scotland, worn mainly by men, nowadays usually to celebrations and on traditional occasions like weddings.
Monsters refer to the tradition that in Loch Ness a monster lurks. The Loch is so deep that it hasn't been explored thoroughly and several people claim to have seen the monster!
A Loch is a lake!
