Is it proper to use thing at the end of sentence?

It's not inherently wrong to use "thing" at the end of a sentence, but it's often considered informal and vague. It's generally better to use more specific and descriptive language.

Here's why:

* Clarity: "Thing" is a very broad term. It doesn't give the reader a clear understanding of what you're referring to.

* Specificity: Using more specific words makes your writing more engaging and informative.

* Formal writing: "Thing" might sound too casual for formal writing, such as academic papers or business documents.

Examples:

Informal: "I forgot to bring the thing."

More specific: "I forgot to bring the book." "I forgot to bring my phone charger."

However, there are exceptions:

* Informal contexts: In casual conversation, "thing" can be perfectly acceptable.

* Emphasizing the unknown: Sometimes, you might intentionally use "thing" to emphasize that something is unknown or unspecified. For example: "I have a feeling something bad is going to happen, I can't put my finger on what thing it is."

Overall, it's best to avoid using "thing" at the end of a sentence unless you have a specific reason for doing so. Try to be more descriptive and specific in your writing.
