Particles and causative? Can someone please explain how and when to use which particles with the causative grammar form? For example, How would you say "I made my friend swim at the pool." 友達をプールでおよがせる。? I made my friend eat with chopsticks? 友達をはしでたべさせる。? Is that right?

”話すことができます”　　”はなせます”　　おなじいみですか。 I'm learning potential forms, and I was wondering if they have the same meaning.

くつとくつしたのカウンター。 そくとおもいます。でもともだちはくつしたは”まい”をつかいます。どちらほうがいいですか。 I think "soku" is used for both, but my friend says we're supposed to use "mai" for socks. What is the correct counter?

verbs and their te forms. When to use te and tte? (て　か　って？） I have a conjugation question. When do I use the small つ？ Which verbs are they used for? Is there a difference?
