Question

During the war , people in the cities were forced to { meaning turn off the lights }

Answer 1

Answer:

If you say “turn off the light”, it could mean one of two things, which are different conceptually but often the same in practice. It could mean “turn off the lamp”, using “light” as a synonym for lamp/light fixture.

But it can also be using the word “light” to mean actual light, a.k.a. visible electromagnetic radiation. In this sense it is like saying “turn off the water”.

If you say “turn off the lights” that indicates you are using “light” in the first meaning, and that there are more than one of them. It would be wrong to say “turn off the lights” if there is only a single lamp, although people would probably not question it.
