Graph是Write or draw的意思。Biography中的bio是life(用biology生物這個字來聯想), 通過字根自首了解是「寫自己的生命」，所以是自傳。Autograph則是寫自己（的名字），所以是簽名。字根自首在一開始的確要花一點時間，但是記住常用的字根自首之後，對需要背大量單字的學習者，有很大幫助的。
Dear Lily, I just came across another clip from you. I agree with your perspectives most of the time. But this one - I have to respectfully disagree what you had to say about the Latin/Greek roots. Using the photograph and geography (geo also means earth which you didn’t mention) was not a great example. It’s like someone who doesn’t understand the essence of it and tries to give the rating. A few good examples: Cent - means hundred: century, centenarian, centipedes (guess which insects have 100 legs) Ped/pod - means legs: pedestrian, tri-pods, podiatrists man - means hand: manufacture, manual mal - means bad: malpractice, malfunction, malice. Seriously, it’s not boring at all. I just wanted to clarify it with your audience. it could be lots of fun memorizing the new vocabulary using Latin/Greek roots especially when you’re learning other romance languages. Students just need to get a right teacher to guide them through.
