Kelly from Peru


I say the idioms naturally, it's very rewarding.

Hi, I'm Seonaid, your teacher


And together with the Perfect English Grammar team, I've helped *tens of millions* of students improve their grammar.

I'm a British native speaker of English. I have a Master's degree (MPhil) from Cambridge University in English and Linguistics and I've been teaching English for 21 years.

I live in London, I've studied French, German, Spanish and Japanese myself and I love learning, culture, books and ideas.
