I want a sovereign ring.
I’m surprised no one has mentioned ‘en suite’ - the bathroom attached to a master bedroom.
All the Americans on house hunter type shows on HGTV used to talk about wanting a ‘master bath,’ now they all want an ‘en suite.’
And what’s so British about ‘booking’ a flight or hotel? I’ve always used the term and people have always known what I meant. And I heard ‘chat up’ as early as the 60s movies, though you don’t hear it too much in regular speech.
Little by little, the fall of the republic... : )
