Log typo misprinted including line written in many languages (8)
I believe the answer is:
polyglot
'in many languages' is the definition.
'log typo misprinted including line' is the wordplay.
'misprinted' indicates an anagram (I've seen 'misprint' mean this).
'including' indicates putting letters inside.
'line' becomes 'l' (used when specifying particular lines from a poem).
'log'+'typo'='logtypo'
'logtypo' is an anagram of 'poyglot'.
'poyglot' placed around 'l' is 'POLYGLOT'.
'written' is the link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for polyglot that I've seen before include "Speaker of many languages" , "Bible" , "One fluent in many languages" , "Using several languages" , "Speaking many languages" .)
