“Let's” vs. “lets”: which is correct?
Lets now see how it can be done.
Let's now see how it can be done.
Is sentence 1 wrong?
Yes, 2 is correct.
This is effectively a duplicate of “Let's” vs. “lets”: which is correct? except with the opposite right answer.
1 could be "correct" (but not a real sentence) if in context it means "(subject, person or object) now lets see how it can be done.", but notice I had to swap "now" and "lets" for even that implied sentence.
