Kinds of information it takes time to get (6)
I believe the answer is:
genera
'kinds of information' is the definition.
'genera' can be an answer for 'kinds' (genus is a kind of kind). I am not sure about the 'of information' bit.
'time to get' is the wordplay.
'time' becomes 'era' (an era is a period of time).
'to' means one lot of letters go next to another (I've seen this in other clues).
'get' becomes 'gen' (I can't justify this - if you can you should give a lot more credence to this answer).
'era' after 'gen' is 'GENERA'.
'it takes' acts as a link.
Can you help me to learn more?
(Other definitions for genera that I've seen before include "Forms" , "similar groups" , "Groups between family and species (biology)" , "Groups with common characteristics" , "Biological groups" .)
