Morphology

longitude = long (opaque) = long + itude

Formally composed of 'long' + the nominalizing suffix '-itude', but the modern sense is a technical geographic term rather than a general 'longness'.

Etymology

Longitude comes from the Latin root longus meaning 'long' and is like the English words long and length. So longitude tells how far east or west a place is on the Earth, a kind of 'long' distance around the globe, which is why maps use it to show a location.
