Morphology

international + Morse + code

The noun phrase is fully compositional: 'Morse' (a signalling system using dots and dashes) + 'code' (a system of symbols) describes the signalling system, and 'international' simply specifies the standard used across countries. This makes the overall meaning directly derivable from the constituents and therefore accessible to a B1 learner who knows the component words.

Etymology

International Morse code comes from the old way of sending messages with short and long signals called dots and dashes that operators tapped or flashed. Because people in many countries learned the same patterns for 'letters' and 'numbers', the system became standard around the world and now means a common code of dots and dashes.
