Tom turns to her, naturally (6)
I believe the answer is:
mother
'tom turns to her naturally' is the definition.
I can't judge whether this definition defines the answer.
'tom turns to her' is the wordplay.
'turns to' is an anagram indicator (I've seen 'turning to' mean this (the letters can turn into other words)).
'tom' with letters rearranged gives 'mot'.
'mot'+'her'='MOTHER'
Can you help me to learn more?
(Other definitions for mother that I've seen before include "Nature so-called" , "Female parent" , "She gives birth" , "She gave birth to her Tom" , "Mum" .)
