Pegs securing the bottom of particular boxes? (5)
I believe the answer is:
trees
'boxes?' 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?
'pegs securing the bottom of particular' is the wordplay.
'pegs' becomes 'tees' (tee is a kind of peg).
'securing' is an insertion indicator.
'the bottom of' says to take the final letters.
The last letter of 'particular' is 'r'.
'tees' enclosing 'r' is 'TREES'.
Can you help me to learn more?
(Other definitions for trees that I've seen before include "Large plants" , "Tall, perennial, woody plant" , "Steer into the plants" , "Components of forest" , "Tall, perennial, woody plants" .)
