Man perhaps in offer to host Games (5)
I believe the answer is:
biped
'man' is the definition.
(humans are an example)
'in offer to host games' is the wordplay.
'in offer' becomes 'bid' (bid is a kind of offer. I am not sure about the 'in' bit.).
'to host' is an insertion indicator (inserted letters are hosted or welcomed).
'games' becomes 'PE' (Physical Education, also called games).
'bid' placed around 'pe' is 'BIPED'.
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for biped that I've seen before include "Walker on two feet" , "One walking on two feet" , "Two-legged creature" , "One standing on two feet" , "Animal walking on two feet" .)
