Explanation

The step giving the reason for the thesis is the hetu.

The classical five-membered inference opens with the thesis, 'the hill has fire.'

The very next member states the ground, 'because it has smoke.'

This is the hetu, the reason cited to establish the proposition.

The hetu supplies the probans on which the thesis rests.
