Small type of bridge over river is perfect for those going a short distance (6)
I believe the answer is:
stroll
'perfect for those going a short distance' is the definition.
I can't tell whether this defines the answer.
'small type of bridge over river' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'type of bridge' becomes 'toll' (I've seen this in another clue).
'over' means one lot of letters goes inside another.
'river' becomes 'r' (abbreviation for river).
'toll' going around 'r' is 'troll'.
's'+'troll'='STROLL'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for stroll that I've seen before include "Meander" , "Amble or ramble" , "A casual, relaxing walk" , "Promenade" , "Constitutional" .)
