adjective INFORMAL

It's a true proposition that originates from an erroneous premise, equivalent to an illogical fallacy.
Relying on the fact that Tim always feels dizzy, he is under the miserroneous assumption that earth circles around the sun. It's actually the fact that he starts drinking at 9 in the morning what makes him dizzy, but even if he didn't, earth would still keep circling the sun and maybe he would stop hitting the floor every now and then.
