Make Tom log on again without a second language (8)
I believe the answer is:
monoglot
'without a second language' is the definition.
(I've seen this before)
'make tom log on' is the wordplay.
'make' indicates anagramming the letters.
'tom'+'log'+'on'='tomlogon'
'tomlogon' is an anagram of 'MONOGLOT'.
'again' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for monoglot that I've seen before include "Speaking or writing only one language" , "Without a second language" .)
