Like a giraffe's day aboard a vessel (7)
I believe the answer is:
african
'like a giraffe's' is the definition.
I can't judge whether this definition defines the answer.
'day aboard a vessel' is the wordplay.
'day' becomes 'fri' (abbreviation for Friday).
'aboard' means one lot of letters goes inside another.
'vessel' becomes 'can' (type of container).
'a'+'can'='acan'
'fri' placed inside 'acan' is 'AFRICAN'.
Can you help me to learn more?
(Other definitions for african that I've seen before include "Bogart's Queen" , "Like some elephants" , "from Liberia?" , "From the second largest continent" , "From one continent" .)
