What is "an arm" as a body part? I mean I've learnt English for almost my whole life, but I see that I get confused at this word. Is it a body part which sticks out of the sholder and ends at the finger tips or it ends which a wrist? If the the latter is true, how to call the whole limb? I will really appreciate your help!

Hello everyone! I've got a question about the phrase "to have experience" and the gerund which follows it. According to Oxford Dictionary we can use prepositions "in" or "of" in such cases like in "I have experience in/of teaching English to kids".

Is it correct not to use preposition between "experience" and "teaching" and why? Which grammatical rule governs it. I would really appreciate your help!
