thinking something out carefully as to achieve complete
comprehension of it;

Excogitation means 'the act of thinking or studying intensely',
and hence 'the result of thinking; a contrivance'."
Excogitation is from excogitate
'to think out; devise; study intensely',
derived
ultimately from Latin excogitare.
It is first found in English
in the early sixteenth century.
"The labour of excogitation is too violent to last long;
the ardour of enquiry will
sometimes give way to idleness or satiety"
(
Samuel Johnson, Rasselas).
"To the excogitation of this problem,
he had devoted many anxious hours"
(Dickens, Our
Mutual Friend).
