Noting unfamiliar words in Ulysses, I cam across arenary, for which I could not find a definition:

Quote:
...dunams of waste arenary soil...


I am no word expert, but I thought that it might mean "sandy." My reasoning:

1. 'Arenary' contains the word 'arena'. Looking at the etymology, 'arena' is related to the Latin 'harena', meaning 'sand'
2. "sandy" is a sensible adjective/ to fit with the word "soil"
