Hi,

Before the clauses beginning with "what" do we have to use prepositions. For example; I have no clue (about) what you just said. If needed; responsible for, good at, etc... If it depends, on what?

Thanks in advance..
johner If it depends, on what?
It depends on if the verb is a phrasal verb or not. These need no preposition:

I heard what you said.

I understood what you meant.

He did what he was told.

She sold what she had in her attic.
Hi,

Thank you. But what about the others? e.g.: don't have a clue, get angry at, take note of, be responsible for, etc.

I don't have a clue about what you're talking about.

I don't have a clue about what you just said.

I'm not responsible for what you've done.

I'm not good at what they told us to do.

Do we need these prepositions?

Thanks again.

These prepositions have nothing to do with "what." They are necessary with any noun phrase, including the what-clauses in your examples. These are phrasal verbs or expressions with prepositions, in which the preposition is part of the meaning.

For example:

I don't have a clue about Brittany Spears's music.

I'm not responsible for my brother's debts.

I'm not good at chess.

The teacher took note of her absence, the third time this week.
Thank you. I think sometimes in movies they don't say these prepositions. For example the other day in a movie I heard this: "I don't have a clue what they mean". So I thought maybe in casual speeches we can omit the prepositions in what-clauses. That's just what I inferred from it.

Thanks again for the feedback.

Yes, you heard correctly. But this is idiomatic, and does not apply to other prepositional expressions.

Hi,

As far as I understand, prepositions that goes just before clauses or noun phrases are necessary. I was thinking about it and I've realized that following sentences I often use don't apply this rule.

I'm not sure which is worse.

I'm not sure if they're coming along.

I'm almost sure I'm making a mistake somewhere.

Yes, I'm sure I'm making a mistake somewhere but can't figure where. I'd appreciate it if someone could help me sort out this "preposition+clause" thing permanantly. Or it'll be haunting me as it already does. Emotion: sad
Hi,

No, a preposition does not come before every noun clause.

A clause can be an indirect question or indirect statement:

I don't know when they are coming.

I don't know if they are coming.

She didn't tell me why they are coming.

etc.

A clause can be an adjective or noun complement:

He was not sure which was worse.

She was confident (that) she would win.

A clause can be a direct object or subject;

He told me (that) he was coming.

Whether she wins or not is of no concern to me.

Do you know that yesterday he said he loved me?

It might be good if you reviewed clauses. Here is a good overview.

Apparently the topic that confuses me is "noun clause as object of preposition". I'm good with the other noun clases. I'll be searching.

Thanks again.
