つづ, A Tsugaru Dialect word, with many meanings.
I haven't heard ofつづand it's Tsugaru Dialect, so I've never said it before.
つづ means soil, governor, cheese, a pipe, father and milk/breast.
I listened to the pronunciation on a video, but I couldn't hear the difference.
I'm Japanese, but there are a lot of Japanese words that I don't know.
