Every Saturday I’ll give you a couple of idioms to learn. An idiom is a saying or phrase whose meaning cannot be taken from the literal meanings of the words.
take a nosedive: decline drastically, plummet
Example:
The price of electronic equipment has taken a nosedive due to the market being flooded with cheap imports.
go through with: fulfill one’s agreement, complete as planned or promised
Example:
