For bonding devices I usually say "bond" and "member" at work, or things like "I added eth4 to bond0," which seems at least as clear as "I enslaved eth4 to bond0". For disks I usually write and say "LV" and "PV" for LVM and "LD" and "PD" for MegaRAID, which matches what the respective CLIs use. Re terminals, it's the end that's connected to the monitor (or terminal emulator), just like the other end is connected to the application/session. There aren't two actual pseudoterminals in any sense, just two views of the same thing, so the idea of "the pty master"/"the pty slave" doesn't quite make sense unless you're very careful to realize you're talking about the open FD and not the actual thing. I'd probably say something like "the monitor end" and "the session end" (and continue to abbreviate them as "ptm"/"pts").
