Compare the first word if match

Answer 1

Assuming Sheet 1 has a range of values like the one below, and column A of Sheet 3 is equated to column A of Sheet 2:

     A        B
--------------------
1  AA BB  test.
2  CC DD  test..
3  EE FF  test...
4  GG HH  test....
5  II JJ  test.....

You can use this formula on column B of Sheet 3:

=VLOOKUP("*" & MID($A1, 1, FIND(" ", $A1)-1) & "*", Sheet1!$A$1:$B$5, 2, FALSE)
