The opening gets laid out for coming and going (5)
I believe the answer is:
tidal
'coming and going' is the definition.
Both the definition and answer are adjectives.
Maybe there's a link between them I don't understand?
'the opening gets laid out' is the wordplay.
'opening' indicates taking the first letters.
'gets' means one lot of letters go next to another.
'out' is an anagram indicator (out can mean wrong or inaccurate).
The first letter of 'the' is 't'.
'laid' anagrammed gives 'idal'.
't'+'idal'='TIDAL'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for tidal that I've seen before include "Ebbing and flooding" , "Concerning regular changes in sea level" , "Concerning the rise and fall of the sea" , "Concerning lunar-driven ocean movements" , "Of sea, rising and falling" .)
