Stinging plant gets daughter annoyed (7)
I believe the answer is:
nettled
'annoyed' is the definition.
(I know that annoyed can be written as nettled)
'stinging plant gets daughter' is the wordplay.
'stinging plant' becomes 'nettle' (I've seen this in another clue).
'gets' means one lot of letters go next to another.
'daughter' becomes 'd' (genealogical abbreviation).
'nettle'+'d'='NETTLED'
(Other definitions for nettled that I've seen before include "becomes annoyed" , "Irritated as by stinging plant" , "Riled" , "Annoyed as by stinging plant" , "annoyed one" .)
