1.) Of or pertaining to an uncle (GNU Collaborative International Dictionary of English).
Etymology: From Latin avunculus, maternal uncle.
"Balthazar Getty also has a loyal clientele at Richard Pryor's auto shop, one of whom, played by Robert Loggia, is an extremely creepy and menacing crime-boss-type figure with a thuggish entourage and a black Mercedes 6.9 with esoteric troubles that he'll trust only Balthazar Getty to diagnose and fix. Robert Loggia clearly has a history with Balthazar Getty and treats Balthazar Getty with a creepy blend of avuncular affection and patronizing ferocity" ("David Lynch Keeps His Head", David Foster Wallace, 1995).
Okay, so I think I got the embedding of the audio pronunciation working. Let me know if it is working in your browser or not. I contemplated just linking to the Dictionary.com audio, but worried that would be frowned upon (I didn't want to credit them either because I think their site sucks). So this really is me you're hearing. Feels sort of weird.
