cloverleaf
Synonym discussion
Sense: noun/1
An 'interchange' is the broadest term for any road junction with grade separation (one road passing over another). A 'cloverleaf' is a specific type of interchange with four curved ramps that form a four-leaf shape when seen from above. A 'junction' is a general UK term for any road meeting point — it may or may not be grade-separated. An 'intersection' refers to roads crossing at the same level, often controlled by traffic lights, unlike a cloverleaf which uses bridges and ramps to keep traffic flowing. For example: 'Turn left at the next junction' refers to any meeting of roads, but 'The new cloverleaf interchange connects the highway to the ring road' describes a specific four-ramp design.

Etymology
A compound of 'clover' (from Old English clāfre) and 'leaf' (from Old English lēaf). The term was first used in the early 20th century because the shape of this type of road junction, when seen from above, resembles a four-leaf clover.
