Help!

... needed in Tremottelandia. These letters apparently make up a 14 letter word meaning 'unlikely'. How unlikely is that?

I was a bit stuck for a blip today, but not half as stuck as we are with the crossword clue. I am off to babysit later, so thought I would get this done first.

Pithy observation no 1:
My desk does not stay clear for long.

PS The clue was "attend me tailor; unlikely". The answer was tatterdemalion (of course!) which is a raggamuffin. Such a person would apparently be unlikely to require the services of a tailor.
Simples!
