Hi pooksahib, I'm not great at explaining stuff, but i'll give it a stab.
The phrase - as it were. wiktionary gives this definition;
"used to indicate that a word or statement is perhaps not exact though practically right."
ie.so to speak,kind of,or sort of.
When faced with an anagram, you need to sort out the available letters into a different order. So an "Anagram from" is a sort, of the letters you have.
I hope this helps, maybe somebody else can explain better than I can.
p.s. What does FAO stand for?
