Son attempted to keep up record, having wall hangings (10)
I believe the answer is:
tapestried
'having wall hangings' is the definition.
I can't judge whether this defines the answer.
'son attempted to keep up record' is the wordplay.
'son' becomes 's' (genealogical abbreviation for son).
'attempted' becomes 'tried' ('try' can be a synonym of 'attempt').
'to keep up' means one lot of letters go next to another (in a down clue, some letters go beneath others).
'record' becomes 'tape' (synonyms).
's'+'tried'='stried'
'stried' put after 'tape' is 'TAPESTRIED'.
Can you help me to learn more?
(Other definitions for tapestried that I've seen before include "with wall hangings" , "containing much embroidery" .)
