Relating to or characteristic of a coxcomb; foolishly vain or exhibiting ridiculous conceit.
From 'coxcomb' + '-ical' (adjectival suffix, from Latin '-icalis'). The '-ical' suffix is more formal than '-y,' creating a more sophisticated-sounding adjective.
The difference between 'coxcomby' and 'coxcomical' is subtle but real—'coxcomby' sounds more casual and spoken, while 'coxcomical' sounds more formal and literary, which is why older writers like Dickens preferred 'coxcomical' to describe their pompous characters.
