Belief held in parts of the internet (5)
I believe the answer is:
tenet
'belief' is the definition.
(synonyms)
'parts of the internet' is the wordplay.
'parts' becomes 'ten' (I am not sure about this - if you are sure you should believe this answer much more).
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'internet' becomes 'e' (I've seen this in other clues).
't'+'e'='te'
'te' with letters rearranged gives 'et'.
'ten'+'et'='TENET'
'held in' is the link.
Can you help me to learn more?
(Other definitions for tenet that I've seen before include "Teaching" , "Matter of belief" , "Doctrine; principle held" , "Belief held as true" , "A palindromic doctrine or belief" .)
