  1. To help she took a dictionary and started to look up words.
  2. Though it was hard we didn’t give up and kept trying to understand each other.

    Thanks.

  1. To help, she took a dictionary and started to look up words.
  • This is not a standalone sentence. The first part of the conversation is important as it would explain what she was trying to help with.

2 is okay. I would place a comma after ‘hard’.

Beeesneees,
“To help herself, she took a dictionary and started to look up words.”
Is the above sentence not a stand alone sentence?
Please comment.
Thanks.

Now that you have added ‘herself’ that is okay.
If you remove ‘herself’ the meaning is not the same. Your sentence in message #1 indicates that she is helping someone else somehow by looking up words.
