Accepts an offer on lease occasionally (6)
I believe the answer is:
abides
'accepts' is the definition.
The answer and definition can be both related to thinking as well as being verbs in their -s form.
Maybe you can see an association between them that I can't see?
'an offer on lease occasionally' is the wordplay.
'an' becomes 'a'.
'offer' becomes 'bid' (synonyms).
'on' means one lot of letters go next to another.
'occasionally' means one should take alternating letters (letters taken at regular intervals or occasions).
The alternating letters of 'lease' are 'es'.
'a'+'bid'+'es'='ABIDES'
Can you help me to learn more?
(Other definitions for abides that I've seen before include "Lives or tolerates" , "Continues without fading or being lost, memory perhaps" , "Dwells or endures" , "Stomachs" , "Lives or endures" .)
