It as a preparatory object

It is sometimes used as a preparatory object. This usually happens when the actual object is an infinitive phrase or a clause with an adjective or noun complement.

Note the structure: subject + verb + it + complement + infinitive / clause

She made it clear that she was not interested in marrying him. (More natural than ‘She made that she was not interested in marrying him clear.’)

He made it clear that he couldn’t accept our proposal.

I find it difficult to work with her.

My health problems made it difficult for me to find a good job.

I thought it strange that she hadn’t returned yet.

James made it clear what he wanted.

Grammar notes

This structure is not normally used when there is no adjective or noun complement after the verb. However, there are some exceptions to this rule. Common examples are: I like it when / I hate it when etc.

I like it when she smiles.

The idiom ‘I take it that’ means ‘I assume that’.

I take it that you won’t be coming with us. (= I assume that you will not be coming with us.)

This structure is also possible when the object is an –ing form.

I find it interesting listening to her speeches.
