Particle split by head of thermodynamics in city abroad (6)
I believe the answer is:
boston
'city abroad' is the definition.
I can't tell whether this defines the answer.
'particle split by head of thermodynamics' is the wordplay.
'particle' becomes 'boson' (boson is a kind of particle).
'split by' means one lot of letters goes inside another.
'head of' suggests taking the first letters.
The initial letter of 'thermodynamics' is 't'.
'boson' going around 't' is 'BOSTON'.
'in' is the link.
Can you help me to learn more?
(Other definitions for boston that I've seen before include "Card game; dance" , "American city noted for historic Tea Party" , "Capital of Massachusetts" , "type of terrier's found" , "Site of rebellious tea party" .)
