Okay, I'm still working on the 'sence, scents, cents' stuff (having such a hard time with that)
But I'm on to then/than. How do you use them? PLEASE use simple terms, thank you very much!

Use "then" to refer to a time: the bald man rejoiced in his vision of heaven, because his pastor told him, "There will be no parting then (at that time)."

Use "then" also when there is an "if" that goes along with it. For example, "if that's what you're saying about me, then frog you!" This case can be a little tricky, because the "if" is often left out or merely implied in conversation. She: Go to blazes, chump. He: Then the same to you!

He's answer above really implies an "if," because what he means is that if she's statement means what he thinks it does, then his statement applies to her, too.

In all other cases, use "than."

Okay, I'll work on it, thanks maiku.

I would place the precision of meaning rather the other way round. 'Than' is only used when there is a comparison - 'more than', 'less than', 'colder than' and so on.

'Then' has its place as maiku says, but can also be used in the rather meaningless 'fill-in' phrase you used in your question, 'Well then ....' or perhaps 'Then ....', having just a weak sense of 'Let's move the conversation on'.

Okay Ewood, thank you. I'm working on it...might have more questions, though.
