Swankier → It is formed from 'swank' (originating from the late 19th century, possibly from the Scottish 'swankie', meaning a swaggering or showy person) and the comparative suffix '-ier' (meaning more). The word 'swankier' means more showy or ostentatious in style or appearance.
Think of someone who is 'showy' or 'swaggering' ('swank') and then imagine them being 'more' ('-ier') so — that's what swankier means.
