Last night a student brought in some copies of drawings made by someone whose last name is "Tsuchiya" (sorry, didn't catch the given name) who had had an exhibition or event at a local museum. The drawings illustrate Yamagata dialect words and phrases. Here are the words and one phrase on those drawings;
こちょぴたい - "Kochopitai" - ticklish
このげ - "Konoge" - eyebrow hair (singular)
たがずく - "Tagazuku" - to cling (to someone else) / clinging
しゃあますする - "Shamasusuru" - to become confused and unsure of what to do (sic)
どさがいぐべ - "Dosa ga igube" - "Let's go that way"
Update Oct 9th: I met the student who brought in the prints in class tonight (she attends two classes a week). The artist's given name is Yoshiharu and he's originally from Tsuruoka. He's known for either illustrating and/or writing children's books. The prints were acquired at the city library and not a museum.
