Sailors in house next to toy maker (6)
I believe the answer is:
hornby
'toy maker' is the definition.
I know nothing about this answer so I can't tell whether this works.
'sailors in house next to' is the wordplay.
'sailors' becomes 'rn' (abbreviation for Royal Navy).
'in' means one lot of letters goes inside another.
'house' becomes 'ho' (abbreviation for house).
'next to' becomes 'by'.
'ho'+'by'='hoby'
'rn' going inside 'hoby' is 'HORNBY'.
Can you help me to learn more?
(Another definition for hornby that I've seen is " Nick --, British author".)
