1) I've recently heard people use the phrasal verb 'hold up' in two different ways dictionaries don't usually list as entries. Is it a new usage? a) Paul: How are you holding up, Joe? = doing, managing, under the circumstances ----- b) Mary: I'll hold up my promise and you'll hold up yours, ok?!  = keep ------------------------------------------------------------------------------------ 2) What is the meaning of the phrase 'Just so...' ? I've seen it usually is followed by the verb 'know': Just so you know...

Hi,

I'll hold up my promise and you'll hold up yours, ok?! 

I haven't heard this with regard to a promise.

What I have heard is I'll hold up my end . . . The idea here is that there is a mutual agreement or bargain of some kind, and that I will do my part, do what I have agreed to do . .

It's similar, but I just haven't heard it with the word 'promise'.

If uou search Google, you get almost no hits for 'hold up my promise' but a reasonable number for 'hold up my end'.

Best wishes, Clive
