Facts say syphilis gets caught by 'resting' close to others (10)
I believe the answer is:
statistics
'facts' is the definition.
The answer and definition can be both related to thinking as well as being plural nouns.
Maybe you can see a link between them that I don't see?
'syphilis gets caught by resting close to others' is the wordplay.
I cannot quite understand how this works, but
'gets' could be 'is' (I've seen this in other clues) and 'is' is located in the answer.
'caught' could be 'c' (cricket abbreviation) and 'c' is found in the answer.
'by' could be 'at' and 'at' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'say' is the link.
Can you help me to learn more?
(Other definitions for statistics that I've seen before include "'20, 16 20, and _____'" , "results" , "Branch of maths" , "(Study of) quantitative data" .)
