Summer’s initial ripening not at first covering everywhere? (10)
I believe the answer is:
saturation
'summer's initial ripening not at first covering everywhere?' is the definition.
I can't judge whether this defines the answer.
'summer's initial ripening not at first' is the wordplay.
'initial' says to take the initial letters.
'ripening' becomes 'maturation' (synonyms).
'not at first' means to remove the first letter.
The initial letter of 'summers' is 's'.
'maturation' with its first letter removed is 'aturation'.
's'+'aturation'='SATURATION'
Can you help me to learn more?
(Another definition for saturation that I've seen is " State of total dampness".)
