hold the fort Meaning If you hold the fort, you look after a place or a business while the person who is normally in charge is away. For example Can you hold the fort while I run down to the bank? Your job will be to serve customers, and occasionally hold the fort if I have to go out. ━━━━━━━━━━━━━ #Idiom_of_the_Day @EnglishoftheDay 3.5K views11:56
