Nose endlessly runs with it (4)
I believe the answer is:
snot
'nose endlessly runs with it' is the definition.
I can't judge whether this definition defines the answer.
'nose endlessly runs with it' is the wordplay.
'endlessly' means to remove the last letter.
'runs' indicates an anagram.
'with' means one lot of letters go next to another.
'it' becomes 't' (abbreviation. e.g. in 'tis).
'nose' with its last letter removed is 'nos'.
'nos' anagrammed gives 'sno'.
'sno'+'t'='SNOT'
Can you help me to learn more?
(Other definitions for snot that I've seen before include "Mucus" , "Contemptible type" , "Dog" .)
