Kind? Bionic? Erm … a little! (4)
I believe the answer is:
nice
'kind?' is the definition.
(I've seen this in another clue)
'bionic? erm a little' is the wordplay.
'a little' indicates the answer is hidden within the clue (a little bit of the clue).
'NICE' can be found hidden inside 'bionic erm'.
(Other definitions for nice that I've seen before include "Attractive Mediterranean resort" , "French seaport in SE - sounds pleasant" , "French Mediterranean resort" , "Enjoyable" , "Delightful - French resort" .)
