Animal in here might trip a tourist, knocking them over (5)
I believe the answer is:
tapir
'animal' is the definition.
(tapir is a type of animal)
'here might trip a tourist knocking them over' is the wordplay.
'trip a' anagrams to 'TAPIR'.
Though, I'm not clear how the anagram is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for tapir that I've seen before include "Nocturnal mammal with a short flexible proboscis" , "I part with the pig-like animal" , "Animal with elongated snout" , "nocturnal beast" , "Tropical hoofed mammal with a flexible proboscis" .)
