Herd of animals runs into bird (5)
I believe the answer is:
drove
'herd of animals' is the definition.
'drove' can be an answer for 'herd' (I've seen this in another clue). I'm not certain of the 'of animals' bit.
'runs into bird' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'into' is an insertion indicator.
'bird' becomes 'dove' (dove is a kind of bird).
'r' inserted into 'dove' is 'DROVE'.
Can you help me to learn more?
(Other definitions for drove that I've seen before include "took to the road" , "Carried along by force" , "Group of animals" , "Travelled by car" , "Took car; herd animals" .)
