I'm going to ask for a little help tonight. Does the following sentence have double negatives, misplaced or dangling modifiers?

"I left my agenda in a restaurant which had all my important dates in it."

There are no negatives -- so that rules that out.

Do you see the misplaced modifier?

Yes, I found it. It was, "all my important dates in it."

Next question. Does this sentence have
double negatives, and how can I revise it?

"In my experience, performing in front of a crowd is not hardly as daunting as it seems."

The entire misplaced modifier is "which had all my important dates in it."

Yes, the second sentence has a double negative -- "not hardly." Just omit one of those words.
. . . is not as daunting as . . .
or
. . . is hardly as daunting as . . .

To determine if the sentence has double negatives, misplaced modifiers, or dangling modifiers, we'll examine each element separately.

Starting with double negatives, these are two negatives used in the same sentence that cancel each other out. In the given sentence, we don't see any double negatives.

Next, we'll check for misplaced modifiers. These occur when a modifier (such as an adjective or adverb) is not placed close enough to the word it is supposed to modify, resulting in confusion or ambiguity. In the sentence, there are no obvious misplaced modifiers.

Lastly, we have dangling modifiers. A dangling modifier is a word or phrase that is intended to modify a specific word but is not clearly connected to it. Again, in the given sentence, there are no notable dangling modifiers.

In conclusion, the sentence "I left my agenda in a restaurant which had all my important dates in it" does not contain any double negatives, misplaced modifiers, or dangling modifiers.
