Cut off most of flaccid object (5)
I believe the answer is:
limit
'cut' is the definition.
The definition and answer can be both related to change as well as being verbs in their base form.
Maybe there's an association between them I don't understand?
'most of flaccid object' is the wordplay.
'most of' means to remove the last letter.
'flaccid' becomes 'limp' (synonyms).
'object' becomes 'it' (pronoun for an inanimate object).
'limp' with its final letter removed is 'lim'.
'lim'+'it'='LIMIT'
'off' is the link.
Can you help me to learn more?
(Other definitions for limit that I've seen before include "Bound, restriction" , "Ceiling" , "verge" , "Curb" , "As far as something can go" .)
