Nominal Clauses
Whole clauses that behave like nouns — sitting in subject, object, and complement positions so you can package a complete idea and slot it into a larger one.
Choose a clause type. A context.
Five clause types, three contexts — 15 hand-built sentences. Watch a whole clause slide into a noun position — subject, object, or complement.

The rules — with examples
How whole clauses take noun positions, which wh-word to choose, and where the subjunctive is required.
The three noun positions
That she resigned surprised us.
I realize (that) you’re busy.
The problem is that nobody checked.
Heavy subjects get extraposed. “That he lied to everyone repeatedly is shocking” is grammatical but front-loaded. English prefers dummy it: “It is shocking that he lied to everyone repeatedly.” As an object, that is often simply dropped.
The clause-type families
Direct vs. embedded — side by side
Whether vs. if: only whether works as a subject (“Whether we succeed depends…”), after a preposition (“depends on whether…”), before a to-infinitive (“unsure whether to go”), and directly before or not. In plain object position, both work: “I doubt whether / if it will help.”
Frames to steal — learn them as chunks
The subjunctive in one line: after a demand, the that-clause verb is the base form for every person — “that he resign”, “that it be signed”, negative “that she not attend”. British English often softens it to should + base: “that he should resign”.

The one rule to remember
A nominal clause is a noun in disguise — it can be a subject, an object, or a complement. When you embed a question inside one, strip out the inversion and the do: statement order always wins. And after a demand (insist, require, it is essential), the verb drops to its base form.
