compare two worksheets and delete duplicates

Hello everyone,

i have two wordlists in two different worksheets "1" and "2". Now i want to delete those rows from worksheet "2" where entry of column A also exists in column A of worksheet "1". No changes should be made to the worksheet "1" but only to "2".

Second problem is that some words in column A of worksheet "2" have wrong spacing which causes problems in comparing both A columns. For example:

worksheet "1" Col. A
lovely
being proud of something
everyone
everybody

worksheet "2" Col. A
love ly
being proudof some thing
every one
someone

Now according to our example i would like to delet three rows in "2" because they are the same as in "1" but with other spacing. That would mean that according to our example, only the last entry of "2" will remain which is "someone" and others should be deleted.

By the way WS "1" contains 12000 entries and WS "2" contains 140,000 entries. In other columns there is also data but column "A"s should only be compared.=> compare cells of colums A and delet complete rows in "2" if entry of column A also exist in column A of WS "1".

I am uploading few rows dummy data as example.

Thank you very much for each help in advance.
