Character seen in first part of book? (3)
I believe the answer is:
chi
This clue could be a double definition.
'character' is the first definition.
(chi is a kind of letter of the alphabet)
'first part of book?' is the second definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'seen in' is the link.
Can you help me to learn more?
(Other definitions for chi that I've seen before include "Greek letter; Chinese life force" , "T'ai -, martial art" , "The life force, according to traditional Chinese medicine" , "seen in Greek writing" , "character from Euripides?" .)
