Someday is used as an adverb. Some day is used when "some" is acting like its determiner self (like the, a, an) and "day" is just a noun. In the case of the song it's someday because it is adding information to the verb join. When will you join? Someday. Best way to tell the difference is to test if "day" is a stand alone noun. Some day is the right day. He will come someday. This also happens with words like everyday, sometime, etc. Hope that helps!

They have the exact same meaning. As being from the US, I would use "one or the other." Perhaps "one or other" is more common in the UK, but, truthully, I don't know. Hope that helps!

"With" is commonly used to mean being in the same space as something or someone. So, if you are with me, we are in the same room or place. It can also mean that whatever I am saying you agree. "with" is a preposition (as you know) "and" is a conjunction Both words serve completely different functions. Because "with" is a preposition, it signals a noun or noun phrase is coming (or something acting like a noun) With me (personal pronoun) With the dog (noun phrase) With going to the park (gerund phrase) Just remember a preposition is always followed by a noun or something acting like a noun.

Here's one way to think about it: "Of" can indicate a part of a whole. "In" can indicate where. Because your example is explaining where to travel, "in" can be used. "Place" or "places" doesn't imply a certain section or part, so "of" would not be used here.

Usually I would use it in a sentence like this: The restaurant is not all it's cracked up to be. In this case it means the restaurant is not as good as its reputation (or reviews, or impressions) said it was. I hear this phrase more often in a negative way like my example sentence, but you could use it positively too like this: The restaurant is all it's cracked up to be. This of course means the restaurant is as good as its reputation. However, using the phrase in a negative way is much more common in my experience. I would also say it's not commonly used anymore. Hope that helps!

Pose is usually a certain position or still shot of someone. Like posing for a picture or a model posing on the runway. Usually yoga pose is the term used as well (not yoga posture). Posture refers to having good body position. Usually back straight as opposed to being hunched over. Yoga posture refers more to having good form instead of the shape the body is in. Pose: body position Posture: how good or bad that body position is Hope that helps!

I would rewrite the sentences this way as a native speaker: John being punctual made me feel happy. The plan, having been carried out, made us feel relieved. Your pairs of sentences both have the same meaning. I'm not sure why verbs are being cut out in each second example. That usually doesn't happen. In both cases, an event is making someone feel something. Because John was punctual (on time), I was happy. Because the plan was carried out (it happened or succeeded), we felt relieved (put at ease, relaxed, no longer worried). Hope that helps! Note for your edit: the last three have the same meaning again. As a native speaker I would only say the first one. Your last sentences indicate two events happening at the same time. He was reading and his wife was knitting (beside or next to him) at the same time.

"At all" in your example means close to "anymore." Something is not popular anymore or any longer. "At all" can also be used like this: That's not right at all. The meaning here is more like "it's completely wrong." Hope that helps!
