'chunky' originates from the word 'chunk,' which comes from the Old Norse word 'kǫnkr,' meaning 'a lump or mass.'

'chunk' evolved from the Old Norse 'kǫnkr' into the Middle English 'chonke,' eventually becoming the modern English word 'chunk.'

Initially, it meant 'a lump or mass,' but over time it evolved into its current meaning of 'thick or solid.'
