Having the qualities or manner of a cavalier; somewhat cavalier in attitude; dismissive, arrogant, or carefree in a way characteristic of historical Cavaliers.
From 'cavalier' with the suffix '-ish,' which creates adjectives meaning 'having the qualities of' or 'somewhat like.' This is a productive English suffix that allows fine-tuning of meaning—'cavalierish' is more qualified than simply 'cavalier,' suggesting shades or hints of the quality.
The '-ish' suffix is linguistically brilliant because it softens judgment—calling someone 'cavalierish' is less harsh than 'cavalier,' implying they have some of that arrogant attitude but maybe not completely. English speakers use it constantly to hedge and nuance.
