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' together with the ending -illion used for very large numbers like 'million'. In the long scale used in older British and European books the 'thirteenth' -illion is much larger, equal to 1 followed by 78 zeros, which is why the term is mainly of historical interest there.
