Some sexagenarians - after retirement - entered a marathon (3)
I believe the answer is:
ran
'entered a marathon' is the definition.
The definition and answer can be both related to competing as well as being past participle verbs.
Maybe you can see an association between them that I can't see?
'some sexagenarians after retirement' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'after retirement' says the letters should be written backwards.
'nar' is hidden in the letters of 'sexagenarians'.
'nar' backwards is 'RAN'.
Can you help me to learn more?
(Other definitions for ran that I've seen before include "Tore" , "Took a single" , "Went fast" , "Moved fast or managed" , "Flowed" .)
