I was amused to see the same tautology in all three letters about the NAHT annual conference (“Fear and loathing in an annual union conference”, Letters, 24 May). After the third appearance of “NAHT headteachers’ union”, I began to suspect editorial tinkering. The subject for “From the forums” on the facing page seemed particularly apt: Is good grammar still important?
