When reading a passage in VOA English, I found a sentence:
The process is no easy task.
It comes to me another sentence:
The process is not an easy task.
What's the difference between them?
Dictionary.Com explains this definition as not a (used before an adjective to convey the opposite of the adjective's meaning)
No can also be followed by comparative adjectives and adverbs:
According to this knowledge we can assume that "no easy task" equals "not an easy task".
I am not an English native speaker.
I would just say that there's no difference in the meaning, that is: There's nothing simple in this process.
So, I agree with @SovereignSun. The sentences are the same and they could be intended as synonyms.
