Last work with small bits of wood (5)
I believe the answer is:
slats
'bits of wood' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'last work with small' is the wordplay.
'work with' is an anagram indicator.
'small' becomes 's' (abbreviation - e.g. clothes size).
'last' anagrammed gives 'slat'.
'slat'+'s'='SLATS'
Can you help me to learn more?
(Another definition for slats that I've seen is " Thin strips of wood or metal".)
