Daughter interrupting a break at sea? (6)
I believe the answer is:
adrift
'at sea?' is the definition.
(drifting at sea)
'daughter interrupting a break' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'interrupting' means one lot of letters goes inside another.
'break' becomes 'rift' (I've seen this in another clue).
'a'+'rift'='arift'
'd' placed inside 'arift' is 'ADRIFT'.
(Other definitions for adrift that I've seen before include "cut loose" , "(Of boat) moving out of control" , "Rudderless, astray" , "Afloat without control" , "Going out of control" .)
