A sentence is defined as a string of words. Therefore a single word can not make a sentence. The shortest acceptable sentence in the English language is "I am."
To be one
If you could write that question, then you already have the answer. It's a word followed by another. You can rarely write a sentence with only one word....
To write a sentence like this, one has to be committed to do one's very best.
You just wrote one!
As a one-word answer to the question, "What are you doing?".
yes you can; Can you write a sentence with the word any in it?
Yes, you can write a sentence with the word right. For example: I like to write about super heroes.
I can write a sentence using the word scorn!
i write the same sentence
One example is "I am proud of our alumni."
a sentence with the word variety
You can't write a sentence that is not a sentence, it is either a sentence or it is not. You can write a sentence that doesn't look like a sentence. For example, "Stop!"; although one word, it is a complete sentence. The subject 'you' is implied, the verb is 'stop', which makes it a complete sentence.
