Types and no more written by hand (5)
I believe the answer is:
norms
'types' is the definition.
The definition and answer can be both related to thinking as well as being plural nouns.
Perhaps you can see a link between them that I don't see?
'and no more written by hand' is the wordplay.
'and' becomes 'n' (common abbreviation for 'and').
'no' becomes 'O' (O resembles 0).
'more' says to put letters next to each other (some letters added to the previous ones).
'written by' is a charade indicator (letters next to each other).
'hand' becomes 'rms' (I am not sure about this - if you are sure you should believe this answer much more).
'n'+'o'+'rms'='NORMS'
Can you help me to learn more?
(Other definitions for norms that I've seen before include "Standards, customs of behaviour" , "Social standards" , "Authorative standards" , "Rules" , "Representative standards as of behaviour" .)
