Slob, you should develop and get very independent without doubt (9)
I believe the answer is:
obviously
'without doubt' is the definition.
(thesaurus)
'slob you should develop and get very independent' is the wordplay.
I cannot really see how this works, but
'you' could be 'u' (I've seen this in other clues) and 'u' is found within the answer.
'very' could be 'v' (abbreviation) and 'v' is found within the answer.
'independent' could be 'i' and 'i' is present in the answer.
an anagram of 'slob' is 'bosl' which is located in the left over letters.
The remaining letters 'oy' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for obviously that I've seen before include "Evidently, plainly" , "Manifestly, unmistakably" , "In an evident manner" , "of course" , "Clearly and unmistakeably" .)
