Trying bit of weed, raver jumps into amorous activity (5-8)
I believe the answer is:
nerve-wracking
'trying' is the definition.
(synonyms)
'bit of weed raver jumps into amorous activity' is the wordplay.
'bit of' suggests taking the first letters.
'jumps' is an anagram indicator (I've seen 'jumping' mean this).
'into' is an insertion indicator.
'amorous activity' becomes 'necking' (necking is a kind of activity. I am not sure about the 'amorous' bit.).
The initial letter of 'weed' is 'w'.
'w'+'raver'='wraver'
'wraver' with letters rearranged gives 'rvewra'.
'rvewra' put within 'necking' is 'NERVE-WRACKING'.
Can you help me to learn more?
(Other definitions for nerve-wracking that I've seen before include "Causing anxiety/stress" , "Causing anxiety" .)
