First person going with daughter to America, has very unruly hair (6)
I believe the answer is:
medusa
'very unruly hair' is the definition.
The answer and definition can be both animals as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'first person going with daughter to america' is the wordplay.
'first person' becomes 'me' (first-person pronoun).
'going with' is a charade indicator (letters next to each other).
'daughter' becomes 'd' (genealogical abbreviation).
'to america' becomes 'usa' (United States of America).
'me'+'d'+'usa'='MEDUSA'
'has' is the link.
Can you help me to learn more?
(Other definitions for medusa that I've seen before include "Gorgon slain by Perseus" , "Form of jellyfish" , "all her visitors got stoned" , "Snake-haired gorgon" , "Monster" .)
