Bird to alight on the track (8)
I believe the answer is:
landrail
'bird' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'alight on the track' is the wordplay.
'alight' becomes 'land' (I've seen this before).
'on' says to put letters next to each other.
'the track' becomes 'rail' (synonyms).
'land'+'rail'='LANDRAIL'
'to' is the link.
Can you help me to learn more?
(Another definition for landrail that I've seen is " It's a harsh call".)
