If you tried to teach English-speaking children with words that start with that letter in German, you'd probably confuse them quite a bit.
- a bear that looks like B
- an orange that looks like O
- a snake that looks like S
- a tree that looks like T
(and so on; that's just what I can think of off the top of my head)
Also, "foreign" is always relative. How about an Ancient Greek referring to the barbarians who have no Greek? And, the author's using Greek while living in China.
