Uninteresting weed seen where ships are laid up (3,4)
I believe the answer is:
dry dock
'where ships are laid up' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'uninteresting weed' is the wordplay.
'uninteresting' becomes 'dry' (dry can mean dull or boring).
'weed' becomes 'dock' (type of weed).
'dry'+'dock'='DRY-DOCK'
'seen' is the link.
Can you help me to learn more?
(Other definitions for dry dock that I've seen before include "Place for hull repairs" , "Ship repair area" , "Waterless harbour used for building or repairing ships" , "where a liner may be built" , "naval repair facility" .)
