Hi there,

What does put in mean in the following sentence:
"Efforts put in over the last year."

Thank you

[Snowcake]

put in = expend

Efforts expended over the last year.

Hi there,

Isn't there the need to use the passive voice?
Efforts were put in over the last year?

Thank you

[Snowcake]

Sorry - I have just seen your post.

Your question is good.

Isn't there the need to use the passive voice

No. Here, 'put (in)' is past participle, as in:

Raw materials used to produce linoleum are quite expensive.

If this helps, the original was not a sentence, but a noun phrase.

[Efforts put in over the last year] were successful.
