Grammar fix
a fundamental difference
basic and important distinction
a very basic and important difference between two things, often used to highlight that they are not just slightly different, but different in a way that really matters.
Hear it in context
Notice where the phrase sounds natural.
There is a fundamental difference between knowing about something and truly understanding it.
In my opinion, there is a fundamental difference between simply memorising facts and developing critical thinking skills, which is why education systems should focus more on the latter.
Fix the pattern
One small grammar move makes it sound right.
Not: There is a fundamental difference of the two methods.
Say: There is a fundamental difference between the two methods.
'Difference BETWEEN X and Y', not 'of'.
Which sounds natural?
Tap the one a native speaker would say.
'There exists' is stilted; in speech natives just say 'there's'.
