"Come through" usually means to succeed or deliver what’s expected, especially when it really matters. For example, if a friend promises to help you move and actually shows up on time with a truck, you could say, “You really came through for me!” It’s often used when someone helps out or finishes something important, just when you need it most.

The phrase "on someone's end" means from a particular person's perspective, responsibility, or part of a situation. It often refers to actions or issues that someone else is dealing with or managing. For example, if something goes wrong in a project, you might say "It seems like there was a problem on Sarah's end," meaning Sarah is responsible for the issue.

"Reach out" is a versatile phrasal verb in English that can have different meanings depending on the context. It's helpful to understand its main uses: it can mean to physically extend your arm to touch or grab something, to contact someone for help or communication (often by phone, email, or social media), or to offer support or connection emotionally. The meaning shifts based on what follows the phrase and the situation it's used in, making it a great example of how English relies on context. By practicing with examples, learners can get comfortable spotting these differences.

A "paycheck" is the money you get from your job, usually every week or two, as payment for the work you've done. It can be a physical check or a direct deposit into your bank account. People often say things like “I can’t wait for my paycheck” when they're looking forward to getting paid. It's basically your reward for all the hours you’ve worked.
