Bully in quiet school determined to bite head of year (5,3)
I believe the answer is:
psych out
'bully' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'quiet school determined to bite head of year' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'school' becomes 'sch' (abbreviation).
'determined' becomes 'out'.
'to bite' means one lot of letters goes inside another (to have a bite can mean to consume).
'head of' suggests taking the first letters.
The initial letter of 'year' is 'y'.
'sch'+'out'='schout'
'schout' placed around 'y' is 'sychout'.
'p'+'sychout'='PSYCH OUT'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for psych out that I've seen before include "Undermine" , "Informally, guess correctly the intentions of another" , "cow" , "Guess correctly the intentions of another (informal)" , "intimidate" .)
