Out-of-date about book and unlikely to change? (6)
I believe the answer is:
stable
'unlikely to change?' is the definition.
I can't tell whether this defines the answer.
'out-of-date about book' is the wordplay.
'out-of-date' becomes 'stale' (I've seen this in another clue).
'about' means one lot of letters goes inside another.
'book' becomes 'b' (abbreviation for book).
'stale' placed around 'b' is 'STABLE'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for stable that I've seen before include "Secure - fast - horses" , "It might accommodate Arab" , "Fixed; secure" , "container for punch, for instance" , "Steadfast, resolute" .)
