Thin and hungry, disposing of starter (5)
I believe the answer is:
reedy
'thin' is the definition.
(as in a thin or reedy voice)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for reedy that I've seen before include "(Of sound) thin in tone" , "full of vegetation" , "edge of some river-banks" , "(Of sound) high and thin" , "Like some of the wind" .)
