Ludwig's WRAP-UP

The phrase "an substantial role" is grammatically incorrect and should be "a substantial role".

It's important to use "a" before words starting with a consonant sound to maintain grammatical accuracy. Alternative phrases like "a major part" or "a key function" can also convey a similar meaning with better clarity. Pay close attention to article usage to avoid such mistakes in writing.
