Badminton lessons initially at home - then daughters had singles match (5,4)
I believe the answer is:
blind date
'singles match' is the definition.
The definition and answer can be both groups as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'badminton lessons initially at home then daughters had' is the wordplay.
'initially' suggests taking the first letters.
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'then' says to put letters next to each other.
'daughters' becomes 'dd' (a genealogical abbreviation for daughter repeated).
'had' becomes 'ate' (e.g. I had an ice cream).
The first letters of 'badminton lessons' is 'bl'.
'bl'+'in'+'dd'+'ate'='BLIND DATE'
Can you help me to learn more?
(Other definitions for blind date that I've seen before include "Romantic meeting with someone unknown" , "Tryst with person unknown" , "Assignation arranged by others" , "Social appointment with stranger" , "Social engagement (entered into with one's eyes closed?)" .)
