[The Squatter of Amon Rûdh]

'Weskit' is a rustic form of 'waistcoat'.

'Rede' is probably used because Tolkien thought it looked better than 'counsel' in the context. I suspect that it also has something to do with the fact that 'rede' is a survival through Middle English of Old English rædan, whereas 'counsel' comes from the Latin consilium via Old French conseil. It could even be that Tolkien was just using a synonym of 'counsel' so as to avoid overuse of either term.
