core核心畫面
組成tetchy + -ness. The ending -ness is English's basic tool for turning an adjective into the name of a quality: kind → kindness, dark → darkness, tetchy → tetchiness. As with tetchily, the y becomes an i before the ending. The ending traces back through Middle English -nesse and Old English -nes to Germanic roots — it is one of the oldest word-building pieces English still uses freely today.
