Could it describe a quarter of tongue? (5)
I believe the answer is:
latin
'tongue?' is the definition.
(Latin is an example)
'could it describe a quarter' is the wordplay.
I cannot quite see how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found in the answer.
'a' is found in the answer.
'quarter' could be 'n' and 'n' is found within the answer.
The remaining letters 'li' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Other definitions for latin that I've seen before include "Old Roman language" , "The language of Virgil" , "A Romance language" , "Learning it 'an honour' (Churchill)" , "Language of old 8 down" .)
