Happy first day of Autumn!! Here we are again with another Berlitz WordMaster for you. 

KEEP TRACK OF   ~の経過をたどる



To keep track of something is to be aware of or keep a record of it. 

keep track ofは、何かの経過を把握している、記録をとり続ける、という意味です。


1. My wife keeps track of how much we spend each month.

2. Airlines keep track of flights and reservations with a network of computers.

3. We have so many meetings in this company that it's difficult to keep track of them!
We'll be here again tomorrow with another Berlitz WordMaster!
