Made to lose track, the girl, embarrassed, was upset (8)
I believe the answer is:
derailed
'made to lose track' is the definition.
I can't tell whether this definition defines the answer.
'girl embarrassed was upset' is the wordplay.
'girl' becomes 'delia' ().
'embarrassed' becomes 'red' (someone may blush or go red when embarrassed).
'was upset' says the letters should be written in reverse (I've seen 'being upset' mean this).
'delia'+'red'='deliared'
'deliared' reversed gives 'DERAILED'.
'the' is the link.
Can you help me to learn more?
(Other definitions for derailed that I've seen before include "Forced off the tracks" , "To be off the track" .)
