The phrase "shore up" is a verb that means to support or strengthen something, usually by adding extra support or stability. Imagine you have a wobbly table; you might put something under one of its legs to make it more stable. That's similar to "shoring up" something.
In more advanced contexts, "shore up" can refer to supporting abstract concepts like relationships, economies, or businesses. For example: - "The company is taking measures to shore up its financial stability after recent losses."
While "shore up" primarily means to support, it can also imply improving or reinforcing something that is weak or unstable, whether physically or metaphorically.
"Shore up" can be considered a phrasal verb, as it combines the verb "shore" with the preposition "up." There are no direct idioms that include this phrase, but it is often used in contexts involving support or stability.
"Shore up" is a versatile term that you can use both in a physical sense (like buildings) and in a metaphorical sense (like economies or relationships).
