"Important" vs "of great importance" Hello! I hope you all have great days I've been paying attention to this structure recently, and I found it is really common English; therefore, I'm writing this task, by the way I've done a lot of searches and checked some grammar books such as "grammar in use"es, yet I haven't found even related results, so I really appreciate it if you could guide me. examples: Climate change is greatly important for human beings due to the fact that it may bring about myriad catastrophes to both the environment and individuals, in a direct way. or Climate change is of great importance for human beings due to the fact that it may bring about myriad catastrophes to both the environment and individuals, in a direct way. what is the difference between these two particular parts of sentences which I mentioned in the topic? In my opinion, there is a slight nuance between these two and "greatly important" is a little stronger; furthermore, "of great importance" is more formal. Nonetheless, I'm not sure, and I don't know the name of the grammatical rule which is much more significant and critical to me, so I will be glad and thankful to use your guidance.
