Here is my question. Can I end a sentence with the word (in)?

Question

Here is an example of my sentence with the word (in) at the end of my sentence.

This alters the way we view lifespan development, as individuals truly never stop evolving and changing their own perceptions and ideas depending on the environment that they find themselves in.

Answer 1

You can.

It would be better to do two things, however:

1. Break up this too-long sentence into two sentences.

2. Write "in which they find themselves" at the end so you can avoid that preposition at the end of the sentence.

Answer 2

Thank you, Writeacher
