Thanks to gillpolack , I learned a new word today: "idiolect."What does this mean, you ask? (You did! I'm sure I heard you.)"In linguistics, an idiolect is an individual's distinctive and unique use of language, including speech. This unique usage encompasses vocabulary, grammar, and pronunciation. Idiolect is the variety of language unique to an individual" (https://en.wikipedia.org/wiki/Idiolect).Which makes me wonder what the linguistic term is for a family's usage. I know my birth family had/has some vocabulary that was rather unusual, at least for the region in which I grew up. I know that many of the more distinctive features of my idiolect are things I "inherited" from my father, who grew up in the Florida panhandle, but are modified by my mother's origins in Ohio.
