Someone shooing the animals so they disperse (7)
I believe the answer is:
scatter
'disperse' is the definition.
(synonyms)
'someone shooing the animals so they' is the wordplay.
I cannot really see how this works, but
'someone' could be 'cat' (cat is a kind of someone) and 'cat' is located in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
The remaining letters 'ser' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for scatter that I've seen before include "Strew over an area" , "Spread" , "Break up" , "Throw in various directions" , "Throw in a random way" .)
