Belle Stewart left us this wonderful little ditty, but I am having a difficult time understanding what is meant by one of her lyrics.

The line in question states: "It was there I spied a weel faurt maid," I can speculate that it means a well built maid, but I have searched the Concise Scots dicitionary and Jamieson's Etymological Dictionary and cannot find the word "faurt".

Does anybody know what this word means and where on earth they learned it?

Thanks
