Less demanding because I learn periodically (6)
I believe the answer is:
easier
'less demanding' is the definition.
(I've seen this in another clue)
'because i learn periodically' is the wordplay.
'because' becomes 'eas' (I can't explain this - if you can you should believe this answer much more).
'periodically' indicates alternate letters (letters must be selected 'every so often').
The alternate letters of 'learn' are 'er'.
'eas'+'i'+'er'='EASIER'
Can you help me to learn more?
(Other definitions for easier that I've seen before include "Less burdensome" , "More effortless" , "Not so hard" , "more like a piece of cake" , "More comfortable or less difficult" .)
