I've arranged bash, it's obvious (7)
I believe the answer is:
evident
'obvious' is the definition.
(similar in meaning)
'i've arranged bash it's' is the wordplay.
'arranged' indicates an anagram.
'bash' becomes 'den' (I can't explain this - if you can you should give a lot more credence to this answer).
'it' becomes ''t' (abbreviation. e.g. in 'tis).
'ive' is an anagram of 'evi'.
'evi'+'den'+'t'='EVIDENT'
Can you help me to learn more?
(Other definitions for evident that I've seen before include "clearly visible" , "Clearly apparent" , "Plain, obvious, clear" , "Quite obvious and clear" , "Conspicuous" .)
