Difference between Illogical and Ludicrous

ILLOGICAL vs LUDICROUS: ADJECTIVE

Ignorant or negligent of the rules of logic or sound reasoning: as, an illogical disputant.
Contrary to the rules of logic or sound reasoning: as, an illogical inference.
Synonyms Inconclusive, inconsequent, unsound, fallacious, sophistical.

Resembling farce
So unreasonable as to invite derision
In this respect laughable is the generic word, but it is also one of the strongest. Funny is the weakest of the list, ranging from the meaning of ‘amusing’ or ‘odd’ down to its colloquial use in the sense of ‘strange.’ Comical still retains a faint suggestion of its origin in connection with the drama, being primarily used in connection with something done or seen, and hence something viewed by the mind: a comical predicament is just such as would be fit for exhibition in a comedy. Droll especially implies the odd or unfamiliar: as, a droll story, idea, fellow. Ludicrous is an advance in strength upon comical, as comical is an advance upon funny. Ridiculous is the only word in the list that throws contempt or even discredit upon the person concerned: it is allowable to tell a ludicrous story about one's friend, but not a story that makes him appear ridiculous. A thing may be ludicrous, etc., on account of its unreasonableness or violation of common sense; if it is ridiculous, it is certainly on that account. That is laughable which simply provokes a hearty laugh.
