I believe that the word, cross, could be a useful lexicon word to unpack for Ulysses. Cross has three different meanings and is a prime word for the use of double entendres. Firstly, cross can mean the intersection of lines, often connoting the religious symbol. It can simultaneously mean angry or annoyed. The last definition refers to the extension or the movement beyond a demarcated space. The theme of religion throughout Ulysses makes Cross all the more important. We have seen Buck Mulligan cross his razor and his mirror; an obvious allusion to the religious cross. There has also been significant discussion of cross-dressing, which employs the latter definition of the word. Men and women extend their clothing (sometimes their identity) beyond the space they are expected to occupy. I suspect that this word may be used by Joyce to obscure or challenge the conception of religion in Ulysses.

I also considered core/corpse/corps and bottom as potential words. These are both more bodily in nature which leads me to think that Joyce might use these sorts of words to elicit double meanings in reference to the body. Bottom means both the butt and the lowest which could be conceivably used interchangeably while still invoking meaningful ambiguity. Corpse refers to the dead body. This definition can be relational to the definition of corps which means a branch of the armed services which leads one to think of death. Core refers to the center or most important part of something, which one could decipher as the body. It will be entertaining to see how Joyce employs semantic complexity and double entendres throughout Ulysses.
