The words "invite" and "request" are often confused, but they have distinct meanings. An "invite" is an offer of hospitality or an invitation to an event, whereas a "request" is a polite or formal demand for something. Invites are typically more informal and friendly, while requests can range from polite to formal depending on the context.

Here are some example sentences to illustrate the difference:

• Invite: "I'd like to invite you to my birthday party." (Meaning: I'm offering you a place at my birthday party.)

• Request: "I request that you submit your assignment by Friday." (Meaning: I'm formally asking you to submit your assignment by Friday.)

• Invite: "We invite you to join us for dinner." (Meaning: We're extending an invitation to you to have dinner with us.)

• Request: "I request a meeting with the manager." (Meaning: I am formally asking to have a meeting with the manager.)

Notice how "invite" implies a more welcoming and social atmosphere, while "request" is more formal and often associated with a demand. Sometimes, a request can be a demand, depending on how it is delivered. However, "invite" is always an offer; it's never a demand.

Here's a helpful tip: If you are offering someone something pleasant or social, use "invite". If you are asking for something, use "request". The word "request" can also be used for things that aren't necessarily pleasant, but you still need to ask for them formally.

Happy learning!
