Evening Standard journalists love coffee! (8)
I believe the answer is:
espresso
'coffee' is the definition.
(espresso is a kind of coffee)
'evening standard journalists love' is the wordplay.
'evening standard' becomes 'es' (this might be a standard abbreviation which I don't know about).
'journalists' becomes 'press' (the press can mean the newspaper industry).
'love' becomes 'o' (love means zero in tennis).
'es'+'press'+'o'='ESPRESSO'
Can you help me to learn more?
(Other definitions for espresso that I've seen before include "It's made by forcing steam through ground coffee beans" , "Steamed coffee" , "Strong black coffee" , "Kind of coffee made with steam" , "Kind of shot" .)
