Give victor space to drive at speed (5)
I believe the answer is:
vroom
'to drive at speed' is the definition.
I can't judge whether this defines the answer.
'give victor space' is the wordplay.
'give' says to put letters next to each other.
'victor' becomes 'V' (phonetic alphabet: alpha, bravo, charlie etc.).
'space' becomes 'room' (enough space or room to do something).
'v' put next to 'room' is 'VROOM'.
Can you help me to learn more?
(Other definitions for vroom that I've seen before include "Exclamation imitating a revving car" , "(Of engine) make roaring sound (colloq.)" , "Sound of a car speeding away" , "Fast-moving car noise" , "loud engine noise" .)
