I hope you are all well today. :)
We all know that hyphenation is used in English in order to clear any confusion in a phrase or sentence. However, hyphens should not be used with 'ly' and "very" adverbs, such as: "The finely tuned engine is roaring." My question is: What if instead of: (ly adverb + past participle) formula we have a (noun+adverb) formula? For example, "That noise was ear piercingly loud!" Should we use a hyphen between 'ear' and 'piercingly'? My grammatical sense tells me so because 'noun+adverb' is a very weird sight to me. Further, would you extend the same rule of non-hyphenation for "very" to the adverb "so"? Meaning, would you write the following phrase with a hyphen or not, "The not so/(very) silent night?" Honestly, I'm very conflicted about adding hyphens or not.
A detailed answer is very much appreciated.
Thank you very much for reading!
