Distributed flyers from field and took flight across centre of Monterey (9)
I believe the answer is:
leafleted
'distributed flyers' is the definition.
(flyer can mean a leaflet)
'field and took flight across centre of monterey' is the wordplay.
'field' becomes 'lea' (lea can mean a meadow or field of grass).
'and' says to put letters next to each other.
'took flight' becomes 'fled' ('flee' can be a synonym of 'take flight').
'across' means one lot of letters goes inside another.
'centre of' says to take the centre.
The centre of 'monterey' is 'te'.
'fled' placed around 'te' is 'fleted'.
'lea'+'fleted'='LEAFLETED'
'from' acts as a link.
(Another definition for leafleted that I've seen is " dropped fliers".)
