Garland given girl having tea at home (5,5)
I believe the answer is:
daisy chain
'garland' is the definition.
(I've seen this before)
'girl having tea at home' is the wordplay.
'girl' becomes 'daisy' (**).
'having' means one lot of letters go next to another.
'tea' becomes 'cha' (cha is a type of tea).
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'daisy'+'cha'+'in'='DAISY-CHAIN'
'given' acts as a link.
(Other definitions for daisy chain that I've seen before include "Connect IT devices" , "String of flowers" , "Simple garland" , "simple floral arrangement" .)
