Though old, managed without a servant (4)
I believe the answer is:
aged
'though old' is the definition.
'aged' can be an answer for 'old' (similar in meaning). I am not sure about the 'though' bit.
'managed without a servant' is the wordplay.
'without' suggests deleting specific letters.
'a servant' becomes 'man' (man is a kind of servant).
'managed' with 'man' removed is 'AGED'.
Can you help me to learn more?
(Other definitions for aged that I've seen before include "Long in the tooth" , "Mature" , "Advanced in years" , "not a modern copy" , "Antiquated" .)
