Tendency to include reading perhaps for education (8)
I believe the answer is:
learning
'education' is the definition.
(learning is a kind of education)
'tendency to include reading perhaps' is the wordplay.
I cannot really see how this works, but
'reading' could be 'r' (one of the traditional three R's of education) and 'r' is present in the answer.
'tendency' could be 'leaning' (leaning is a kind of tendency) and 'leaning' is found within the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for learning that I've seen before include "Cognitive process of acquiring skill or knowledge" , "Acquired knowledge" , "information" , "Aquiring skill or knowledge" , "The gaining of knowledge" .)
