One steering to avoid hard wooden thing (3)
I believe the answer is:
elm
'one steering to avoid hard wooden thing' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for elm that I've seen before include "Native British tree" , "wood used in pelmets" , "Deciduous tree with light serrated leaves" , "Tree with a Dutch disease" , "Forest tree" .)
