This time, starts meditating on one she had upbraided (10)
I believe the answer is:
admonished
'upbraided' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Maybe there's a link between them I don't understand?
'this time starts meditating on one she had' is the wordplay.
'this time' becomes 'AD' (AD, Anno Domini, as opposed to BC, Before Christ).
'starts' says to take the initial letters.
'one' becomes 'i' (Roman numeral).
'she had' becomes 'she'd'.
The first letter of 'meditating' is 'm'.
'ad'+'m'+'on'+'i'+'shed'='ADMONISHED'
Can you help me to learn more?
(Other definitions for admonished that I've seen before include "given slap on the wrist?" , "Rebuked" , "Reproved" , "Told off" .)
