to iron out
to remove minor problems: We should be able to iron out these issues once the project has got started.
to jazz (something) up
to make more interesting: I think we need to jazz up the sales brochure with more pictures, more colour etc.
to jot (something) down
to make brief notes: Give me a minute to jot down this idea before we move to the next point.
to jump at (the chance)
to accept eagerly: They offered us much more work than we were expecting and we jumped at the chance to do it. It could be our big break.
to jump on
to criticise strongly: I suggested we offer this part of the work to the graphics team. After all – it is design work. But she totally jumped on me. So we’re going to be doing it ourselves.
