Morphology

event + of + 9/11

The phrase is compositionally built from 'event' + 'of' + '9/11' so its meaning (‘the incident on September 11, 2001’) is directly derivable from the constituents. While it does rely on the learner's cultural knowledge of what '9/11' labels, that label is lexicalized; a B1 learner who knows the constituents (including the meaning of '9/11') will readily understand the MWE.

Etymology
