Notable fear oddly facing tailless rodent (6)
I believe the answer is:
famous
'notable' is the definition.
(I know that notable can be written as famous)
'fear oddly facing tailless rodent' is the wordplay.
'oddly' means one should take alternating letters (letters in the odd-numbered positions are used).
'facing' is a charade indicator (letters next to each other).
'tailless' means to remove the last letter (the tail of the word is removed).
'rodent' becomes 'mouse' (mouse is a kind of rodent).
The alternate letters of 'fear' are 'fa'.
'mouse' with its final letter taken away is 'mous'.
'fa'+'mous'='FAMOUS'
(Other definitions for famous that I've seen before include "Renowned, noted" , "Acclaimed" , "Known and esteemed" , "Well known" , "Known-of widely" .)
