Princess with instrument lacking concentration? (6)
I believe the answer is:
dilute
'princess with instrument lacking concentration?' is the definition.
I can't judge whether this defines the answer.
'princess with instrument' is the wordplay.
'princess' becomes 'di' (Princess Diana).
'with' means one lot of letters go next to another.
'instrument' becomes 'lute' (lute is a kind of instrument).
'di'+'lute'='DILUTE'
Can you help me to learn more?
(Other definitions for dilute that I've seen before include "having less concentration" , "Make (a liquid) thinner" , "Adulterate" , "The time when something ceases to have validity" , "not neat" .)
