conjunction

I looked up unless in an online dictionary and discovered that it can additionally be used as a preposition in the sense of “except for”, but again that would not seem to apply to this sentence as disciplined is an adjective.

Only is an adjective or adverb.

Unless means the same as if…not. Like if, unless is followed by a present tense, a past tense, or a past perfect tense (never by a conditional). Unless is used instead of if…not in conditional sentences of all types. The order of the clauses doesn’t matter with sentences using unless.

used to say what will or will not happen if something else does not happen or is not true; except if: She won’t go unless you go (= If you do not go, she will not go either, but if you go, she will go).

We use the conjunction unless to mean ‘except if’. The clause which follows unless is a subordinate clause (sc): it needs a main clause (mc) to make a complete sentence. When unless comes before the main clause, we use a comma: Unless [SC]it rains, [MC]we’ll go for a picnic by the river tomorrow.

Unless sentence example

2. They wouldn’t all be there unless something terrible had happened.
3. Unless we know where to look, we won’t find where his base is.
4. Not unless he’s willing to make a deal with me.

As you probably already know, “if” is conditional. It is used to describe a possible situation, and what would happen under the conditions of that situation. “Unless” is also conditional, but it is effectively “if” with an extra exclusion or negative qualifier added. Unless basically means “except if” or “if… not”.

An adverb clause of time shows when something happens. It is usually introduced by time adverbs. Examples are: before, after, as, when, while, until, as soon as, since, no sooner than, as long as etc. Note that all adverb clauses are subordinate clauses.

While is not an adverb; it is the entire phrase headed by while which acts as an adverb. In traditional grammar while is classified as a subordinating conjunction, because it joins a full declarative subordinate clause (you sleep in your example) to the main clause.

The word ‘unless’ is a conjunction.

The unless prefix and suffix is used for creating a conditional clause which determines whether a statement or exit clause should be evaluated or not. It may be seen as a compact alternative to the full if.. end if statement.

unless (conj.) The first syllable originally was on, but the quality of negation in the word and the lack of stress changed it to un-. “Except could once be used as a synonym for unless, but the words have now drawn entirely apart” [Century Dictionary].

Without is a preposition. It cannot be used as a conjunction. Unless is a conjunction.

The easiest way to explain “unless” is to say it is the equivalent of a negative if-clause. If I do NOT win the lottery, I will not be able to buy a car. Unless I win the lottery, I will not be able to buy a car.
