Word
insofar as
Definition
fixed phrase. to the degree or extent that something is true. You use this when you want to explain that a statement only applies in a specific way or up to a certain point.
fixed phrase. a subordinating conjunction used to specify the degree or extent to which a statement is valid. It functions as a restrictive qualifier, often introducing a clause that limits the scope of the preceding claim.
Examples
“The plan is good insofar as it saves us money.”
“The new law is a success insofar as it reduces crime, but it has created other social problems.”
“The theory remains robust insofar as the initial conditions are met, though it fails to account for extreme environmental variables.”
Examples
simple
“The plan is good insofar as it saves us money.”
contextual
“The new law is a success insofar as it reduces crime, but it has created other social problems.”
complex
“The theory remains robust insofar as the initial conditions are met, though it fails to account for extreme environmental variables.”
Usage
usually followed by a clause starting with 'as' or 'that'; it is highly formal and common in academic or legal writing.
Teaching tip
teach this alongside 'to the extent that' as a more formal synonym; it is useful for students writing academic essays who need to qualify their arguments precisely.
Pitfall
in so far as
insofar as
while 'in so far as' is sometimes seen, the modern standard in both American and British English is to write 'insofar' as a single word.
