Lend him a rod

You can, but the repetition of "rod" is a little awkward. You might want to say "John forgot to bring his rod. He asked Peter to lend him one."

Thanks. Can I say,

(a) Last Sunday was sunny. John and Peter went fishing. John's rod caught two fish. It was a happy day for both of them.

(b) He lend a rod to Peter because he had no rod to fish.

(c) He lend out his fishing rod.

(a) Usually you would just say "John caught two fish" rather than "John's rod caught two fish." What you wrote isn't actually wrong though.

A series of consecutive very short sentences is often not good style; it gives the text a "staccato" feel. However, if you're learning the rudiments of English then it's fine to do this. In fact, I think you should do more of it, rather than t

Thanks. I try:

Last Sunday was sunny. John and Peter went fishing. John caught two fish. It was a happy day for both of them.

Am I right?
