What are some words that are only often used in one type of sentence?

My favourite Disney character is Figment. See, more than one sentence.
I don’t think any words can only be used in one situation or context.

I think figment only appears in “figment of your imagination” because figment means “something made up or contrived”, so the “of your imagination” is actually a bit redundant.

Here is a previous thread on the topic.

Affidavit?

Thanks, @the100thmonkey. I knew the thread was out there, but I hadn’t been able to locate it.

Is collateral used as an adjective for anything other than damage?

Yes, @LostInParadise. Here are some examples as an adjective.

“Marketing collateral” is an expression used in business. Also you may be expected to provide collateral for a loan.

I said when used as an adjective.

Are there any non-innocent bystanders?
The only time I have heard the word iota used is in the phrase “not one iota of difference.”
Popular use of the word postpartum seems to be limited to postpartum depression.

The questions you are asking are answered by a two minute google.

How many of those uses of collateral have you heard or made use of?

What relevance does that have?

Because I am making a distinction between technical and popular use of terms. For the vast majority, these terms have uses restricted to certain associated words.

Your distinction is meaningless.

And I answered with a link, @LostInParadise. But @the100thmonkey‘s link is better.
