In a position to give a broad smile (5)
I believe the answer is:
abeam
'in a position' is the definition.
I can't judge whether this defines the answer.
'give a broad smile' is the wordplay.
'give' is a charade indicator (letters next to each other).
'broad smile' becomes 'beam' (I've seen this before).
'a' next to 'beam' is 'ABEAM'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for abeam that I've seen before include "At right angles to ship's length" , "At right-angles to keel" , "across width of ship" , "Position relative to ship" , "at right angles to vessel" .)
