To conclude is to bring something to an end or to decide something after thinking about the evidence. It can refer to finishing an event or forming a final judgment.
From Latin 'conclūdere', meaning 'to shut up, enclose, finish', from 'com-' and 'clūdere' ('to close'). The sense of 'closing' became both 'ending' and 'deciding' in English.
When you 'draw a conclusion', you’re mentally closing the case, like a judge shutting a file. That’s why good thinking often means delaying your conclusion until you’ve really examined the evidence.
