Leading astronaut Aldrin excited to tour space, producing this? (9)
I believe the answer is:
adrenalin
'this?' is the definition.
The definition suggests a singular noun which matches the answer.
'leading astronaut aldrin excited to tour space' is the wordplay.
'leading' says to take the initial letters (the leading letter of the word).
'excited' indicates an anagram.
'to tour' is an insertion indicator (to tour can mean to go around).
'space' becomes 'en' (in printing, a space as wide as a letter 'n').
The initial letter of 'astronaut' is 'a'.
'a'+'aldrin'='aaldrin'
'aaldrin' is an anagram of 'adralin'.
'adralin' going around 'en' is 'ADRENALIN'.
'producing' acts as a link.
Can you help me to learn more?
