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' (synonyms. I am not sure about the 'in' bit.).
'to host' means one lot of letters goes inside another (inserted letters are hosted or welcomed).
'games' becomes 'PE' (abbreviation for Physical Education).
'bid' placed around 'pe' is 'BIPED'.
'perhaps' is the 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" .)
