What Does "in light of" Mean?

• Grammatical function: expresses cause or reason; introduces information that provides context for understanding or explaining a subsequent statement.
• Typical sentence position: often initial, but can also appear medially.

How to Use It

• Syntactic patterns: Typically followed by a noun phrase or a clause introduced by "the fact that." It's often followed by a comma, especially when used at the beginning of a sentence.
• Punctuation rules: A comma usually follows "in light of" when it starts a sentence. If it appears mid-sentence, it might be set off by commas if it interrupts the flow of the sentence.
