capcyus, from Latin

Captious comes from Latin
captio, which refers to a deception or verbal quibble. Arguments labeled captious are likely to 'capture' a person; they often entrap through subtly deceptive reasoning or trifling points. A captious individual is one who might also be dubbed 'hypercritical', the sort of carping, censorious critic only too ready to point out minor faults and raise objections on trivial grounds.
