“Our success was largely due to Adele's contributions.”
Your former employee is applying for a new job and has asked you to write a letter of recommendation. In your letter, you're describing a project that she was really helpful with. You have described how successful that project was, and conclude by saying this.
Our success was largely due to Adele's contributions.
"Largely" means "mostly". It's a more formal word which people use in writing or when trying to sound smart in a discussion. Words that commonly appear after "largely" include:
largely because of ___
largely due to ___
"Due to ___" explains expresses the cause of something.
You use "due to" in slightly formal situations. For example, an announcement on a train might include "due to ___":
Due to construction, the uptown 1 train will not be stopping at 50th Street, 59th, or 63rd. The next stop is 72nd Street.
The thing that follows "due to ___" should be a noun. As another example, if something happened because it's raining, you don't say "due to it's raining". You have to use a noun:
The game has been postponed due to rain.
If you want to say that the reason for something was an action, you have to find a way to make that action into a noun. For example:
The project was a failure due to lack of communication between team members.
The action in this sentence is "team members didn't communicate". But to put it in noun form, you say "lack of communication. You could also say:
The project was a failure due to team members not communicating.
In this example, "team members not communicating" acts as a noun.
"Due to" can fit into a sentence two different ways:
- (something) is due to (something)
- (something happens) due to (something)
Your "contributions" are the things that you give to a group project or effort. Your "contributions" can be money, work, or even opinions and ideas.
In the example above, "Adele's contributions" probably means the good ideas that Adele suggested.
