Craft done initially in what manner? (4)
I believe the answer is:
dhow
'craft' is the definition.
(dhow is a kind of craft)
'done initially in what manner?' is the wordplay.
'initially' suggests taking the first letters.
'in what manner?' becomes 'how' (synonyms).
The first letter of 'done' is 'd'.
'd'+'how'='DHOW'
(Other definitions for dhow that I've seen before include "Arabian two-master" , "Arab lateen-rigged sailing ship" , "Arab sailer" , "Arab sailing vessel" , "Type of boat used in the Indian ocean" .)
