With effort, lift some sheaves (5)
I believe the answer is:
heave
'with effort lift' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'some sheaves' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'HEAVE' is hidden in the letters of 'sheaves'.
Can you help me to learn more?
(Other definitions for heave that I've seen before include "cast like this" , "Throw with force - retch" , "Throw; haul by rope (naut.)" , "Pull something heavy" , "Gasp" .)
