A lot of team having the same set of beliefs (5)
I believe the answer is:
credo
'beliefs' is the definition.
(a credo is a statement of someone's beliefs)
'a lot of team having the same set' is the wordplay.
'a lot of' means to remove the last letter (a lot of but not all of the word).
'team' becomes 'crew' (crew is a kind of team).
'having' says to put letters next to each other.
'the same set' becomes 'do' (synonyms. I am not sure about the 'same' bit.).
'crew' with its final letter taken off is 'cre'.
'cre'+'do'='CREDO'
'of' is the link.
Can you help me to learn more?
(Other definitions for credo that I've seen before include "Statement of faith" , "Guiding principles" , "System of principles" , "Apostles' beliefs" , "piece of sacred music" .)
