Thought deeply about poorly timed date (9)
I believe the answer is:
meditated
'thought deeply' is the definition.
'meditated' can be an answer for 'thought' (meditating is a kind of thinking). I am unsure of the 'deeply' bit.
'poorly timed date' is the wordplay.
'poorly' indicates an anagram (a poor spelling).
'timed'+'date'='timeddate'
'timeddate' anagrammed gives 'MEDITATED'.
'about' is the link.
Can you help me to learn more?
(Other definitions for meditated that I've seen before include "Engaged in religious contemplation" , "thought" , "Engaged in spiritual contemplation" , "pondered" .)
