Ookini is a typical osakaben word mostly used by elderly shopkeepers to say “thank you”. Originally, “ookini” meant “a lot of” something or “very”. You could find it in phrases like “ookini arigato” or “ookini gokurosan” (“thanks for your hard work”). The pronunciation of “ookini” differs somewhat for men and women. Women lift their voice slightly on the middle syllable (oo-KI-ni) while men accent the first syllable.
