At first you use carpet combs, anxiously searching for Adam's needles (6)
I believe the answer is:
yuccas
'adam's needles' is the definition.
The answer and definition can be both plants as well as being plural nouns.
Perhaps there's a link between them I don't understand?
'at first you use carpet combs anxiously searching' is the wordplay.
'at first' suggests taking the first letters.
The initial letters of 'you use carpet combs anxiously searching' is 'YUCCAS'.
'for' is the link.
Can you help me to learn more?
(Other definitions for yuccas that I've seen before include "... tropical American plants" , "Spanish daggers" , "Evergreen plants with tall stout stems" .)
