Morphology

tredecillion = tredec + illion

The components 'tredec' and 'illion' do not correspond to recognizable English words or morphemes for most learners, making the meaning opaque.

Etymology

Tredecillion comes from the Latin tredecim 'thirteen' and the ending -illion, like in 'million' and 'billion'. In the American short scale this name marks the thirteenth -illion, which is 1 followed by 42 zeros, so it explains why the number is so huge.
