thus, therefore and hence are different
A simple way of distinguishing and using these words accurately:
1. ‘Thus’ means ‘in this/that way’ - it relates to ‘HOW’ - the manner in which - this or that happens or comes about. It has a practical flavour. eg.Traditionally, you arrange things thus = Traditionally, this is how you arrange things
2 .’Therefore’ means ‘for this reason’, or ‘because of this or that’ - it relates to deductive reasoning, it tells WHY this or that is so, or happened. eg. He was late and therefore missed the bus = he was late and for this reason missed the bus
3. ‘Hence’ means ‘from this/that’ - it relates to WHERE - position, or point in time; it tells from where or what, or to where or what, something comes, derives, or goes eg. -i. Get thee hence! = Get yourself away from here! -ii. Henceforth all entrances will be guarded = From now on all entrances will be guarded -iii. She got the job - hence her good spirits = She got the job and her good spirits derive from that fact. (Note the different slant to ‘therefore’, which would also fit, but would say ” her good spirits are due to (’because of’; ‘for that reason’) that”.
