Amend bit of text without much force (5)
I believe the answer is:
tweak
'amend bit' is the definition.
I can't tell whether this defines the answer.
'text without much force' is the wordplay.
'text' becomes 'sutra' (I have seen 'sacred text' mean 'sutra' so perhaps 'text' could also mean 'sutra').
'without much' indicates the central letters (many letters are removed).
'force' becomes 'weak' (weak force is a kind of force).
The central letter of 'sutra' is 't'.
't'+'weak'='TWEAK'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for tweak that I've seen before include "spin, thus?" , "Slightly shift" , "Slightly alter" , "Fine tune" , "Minor change" .)
