Kind of dash astride horse in St Albans or Telford? (6)
I believe the answer is:
eponym
'st albans or telford?' is the definition.
I can't tell whether this definition defines the answer.
'kind of dash astride horse' is the wordplay.
'kind of dash' becomes 'em' (an em dash is a dash as wide as a letter 'm').
'astride' means one lot of letters goes inside another.
'horse' becomes 'pony' (pony is a kind of horse).
'em' enclosing 'pony' is 'EPONYM'.
'in' is the link.
Can you help me to learn more?
(Other definitions for eponym that I've seen before include "Name of person after whom something is named" , "such as Black Beauty" , "Distinguishing title; derived name" , "eg 'Jane Eyre'" , "Place-name derived from name of a person" .)
