Ran into heads of regulatory enforcement from The Yard, for example? (5)
I believe the answer is:
metre
'the yard for example?' is the definition.
I can't tell whether this defines the answer.
'ran into heads of regulatory enforcement' is the wordplay.
'ran into' becomes 'met'.
'heads of' suggests taking the first letters.
The initial letters of 'regulatory enforcement' is 're'.
'met'+'re'='METRE'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for metre that I've seen before include "Approximately 39 inches" , "Beat pattern (mus.)" , "Rhythmic arrangement of syllables in verse" , "three and a bit of a fourth" , "1.094 yards" .)
