Yesterday's ten letter OUTCLASSED game

[Jacki]

So I missed DUCTLESS and CASTLED. I truly find it amazing that either would be classed as common. It’s not just sour grapes, it’s more that I can’t imagine using them in day to day life and indeed unless Ductless is some sort of commonly used technical term known the world over, I don’t think I’ve ever heard of either of them. Maybe a ductless vacuum system, but no, on reflection, it’s called a ducted system.
So I would like Alan to please reassess their status. Thank you.

I don’t play chess myself but castled is a very common move for those that do.

CHESS
(of the king) moved from its original square two squares along the back rank toward the corner square of a rook, which has been transferred to the square passed over by the king.
"an attack against a castled king is a very important part of the middle game"

Ah, thanks for that - when I pressed on the meaning it talked about having lots of castles. Not really a thing these days! But a chess move would account for its common status.

Some dictionaries tell us that ductless can be used of a gland that secretes hormones directly into the bloodstream. However, the vast majority of usage instances I found were describing air conditioning systems that blow cooled or heated air directly into a room, rather than piping it around the house. While the meaning is fairly obvious when you see the word, lots of us may never have done so. I suspect most people who have air conditioners in their homes would not have thought of them as 'ductless'.

The word will be treated as rare from now on.

Thank you Alan
