I think it's absolutely different words. "Teacher" is associated with the person giving knowledge. "Tutor" is more like a mentor

I would say that teacher is a proffesional and qualificied language "coach" who is trained to show you the structure language, grammar and rules. A tutor is someone who wants to help you in your way, and his/her knowledge are natural because he/she is a native speaker on the language you are learning, but he/she hasn´t studied specific courses. I reckon.

A few days ago, I posted the following question: I would like to thank the following italki members who responded to my question: Tahar, Bleh, Aamer, Elena, NoAgenda, true.amitie, and Fedor. All of your responses were well-thought out and had many similaraties. Here is a summary of your responses: Teachers complete university level programs that qualify them to teach; anyone can act as a tutor: Teachers must follow a curriculum, develop lesson plans, introduce topics (for the first time), explain the topic, and test the student's understanding of the topic; a tutor focuses on the topics that students did not understand and tries to find alternate (other) ways of explaining the topic so that the student will understand the topic: Teachers are limited by their schedules and simply don't have enough time to assist those students that are struggling; a tutor has much more time to work with the student; Teachers are limited by the text book and often do not have enough examples to review with the students; a tutor can reasearch and review many examples with the student, thereby (by doing that) improving the student's ability to use the newly learned material, and: Teachers teach in a school whereas a tutor may assist the student at school or at home. My definitions of a teacher and a tutor inlcudes all of the above. The most significant (important) difference is that a tutor must find a way of explaining the topic in simple terms and may be required to suggest more than one way to understand the topic. A tutor also has much more time to work with the student as compared to a teacher. Finally, the tutor's job is not complete until the student can demonstrate that he or she finally understands the topic and is able to apply the new knowledge and skills. Once again, thanks to everyone who contributed to this question. Please feel free to comment...
