Answer:
His name was Geoffrey of Monmouth.
Explanation:
Geoffrey of Monmouth was a cleric born between 1095 and 1100 who is famous to this day for his influence over the Arthurian myths. Much of his life cannot be accounted for since information is scarce. We do not know precisely where he was born; some sources say he was Welsh, others say he was British. The exact year when he was born is also controversial.
Geoffrey was the author of the "History of the Kings of Britain", or Historia Regum Britanniae, which was translated into several languages. Nowadays, this work is considered unreliable. But Geoffrey's earliest work was probably the Prophecies of Merlin which, as its name reveals, contains a number of prophecies attributed to the wizard Merlin. Some say the character Merlin was created by Geoffrey himself, but Geoffrey claimed to have based him in older Brittonic traditions.
I used to have a teacher who said this as well. The best way to understand would be to show examples of how to specify such terms as “stuff” and “things”. For instance: “The birds have lots of stuff.” That was not clear because the reader does not know what the “stuff” is. Instead, the text could be changed to: “The birds have lots of feathers.” Now the reader knows what the stuff is because it has been replaced with a more specific word. If you go over multiple examples in your head, it will become easier to comprehend and you will get used to doing it.
At the minimum, a prepositional phrase will begin with a preposition and end with a noun, pronoun, gerund, or clause, the "object" of the preposition. In = preposition; the, weedy, overgrown = modifiers; garden = noun.
