Moving here soon, such a tiny town (3-5)
I believe the answer is:
one-horse
'such a tiny town' is the definition.
I can't tell whether this definition defines the answer.
'moving here soon' is the wordplay.
'moving' indicates anagramming the letters (letters are moved around).
'here'+'soon'='heresoon'
'heresoon' is an anagram of 'ONE-HORSE'.
Can you help me to learn more?
(Other definitions for one-horse that I've seen before include "Drawn by a single nag" , "Small, remote and insignificant (place)" , "Small town, with only one quadruped?" , "Small, like a buggy?" , "(Of a place) poor and lacking amenities" .)
