mod

vt.,n.

[very common]

1. Short for ‘modify’ or ‘modification’. Very commonly used — in fact the full terms are considered markers that one is being formal. The plural ‘mods’ is used esp. with reference to bug fixes or minor design changes in hardware or software, most esp. with respect to patch sets or a diff. See also case mod.

2. Short for modulo but used only for its techspeak sense.
