A former vicar turned author has been asked to leave a Truro secondary school because he used "inappropriate language" during a talk.
Mr Taylor denied using inappropriate language
Teachers told GP Taylor, who wrote best seller Shadowmancer, to stop his talk at Penair School after using words such as "bum" and "ass" to 12-year-olds.
Mr Taylor, who was on a nationwide tour promoting modern language, said children were used to such words.
But headteacher Barbara Vann said Mr Taylor's language was "inappropriate."
She said: "We know children will use inappropriate language but we don't have staff using that language.
"It would seem as if we are condoning inappropriate language and we don't."
She said words used by Mr Taylor included "fart" and "pee".
Mrs Vann said: "He is a national novelist and I would expect him to be able to speak to young people without using that sort of language.
"His language was going to go even further but he stopped himself. He started to use the F word and that is not acceptable in a school environment."
She said the talk, organised by local bookshop Ottakar's, got off to a bad start when Mr Taylor "launched himself" into the middle of the children for a photo session.
"We all believe there was an error of judgement and with hindsight he should realise it is not an appropriate way to behave."
Mr Taylor, from Scarborough, said: "If you stand in any playground you will hear language that is far in excess of that.
"English has changed and inappropriate language is now part of everyday language of teenagers.
"The word ass is not used as a swear word and it is used to describe part of the anatomy - bum."
He added: "I am an ordained Anglican minister so I am used to large crowds.
"The kids were obviously interested. I thought they could just be told to calm down."
Ottakar's store manager Andrew Forster said he supported the school's decision and that the language was inappropriate for 12-year-olds.
