And we continue this series of idioms with the letter -K-
What it means:
If you keep something, or someone, at bay it means that you are preventing them from coming too close, whether it is physically or metaphorically. (Also hold something at bay)
When to use it:
Let’s have a look at the physical aspect of it. If you keep someone at bay, you do what you can to keep them far from you. A typical example could be an overprotective dad keeping any of his daughter’s suitors at bay and scaring them (Who has a dad like that? Mine used to say that he would cut all my future boyfriends’ ears and make them pointy like elves…Do not ask me why…You know, funny dads!)
But then I also mentioned a metaphorical aspect. By this, I am actually referring to abstract things such as sadness or hunger. I could for instance say that a nice cup of tea keeps the cold at bay in winter.
Other interesting idioms in K:
Keep a straight face – To stay serious and not to laugh despite wanting to.
Kick a habit – Stop doing something (that you are used to doing)
Knight in shining armour – A person who saves you when you are in great trouble
