We are grateful to the National Association of Schoolmasters Union of Women Teachers for its latest puzzler sent to members and their staffrooms.
Spelling out its pay policy, the union states: "The three-year agreement reached in the McCrone negotiations is currently the high-water mark of these Desideranda".
Desideranda? Some scholars believe this is inaccurate, others say not - but it is certainly an academic challenge.
And we thought that Tino Ferri, the great Latin scholar, had moved on.
Learned officials obviously remain.
