When we need to explain or clarify something we have already said, we often use phrases to indicate to the listener that we are going to say the same thing in a different way.
For example:
Which simply/just/basically means…
And what it/this/that means is…
What I mean by that is…
By which I mean…
What I’m trying to say is…
Which is to say…
To put it simply…
That is to say…
Or to put it another way…
In other words…
NB: We can also use “i.e.” (that is) or “meaning” to paraphrase.
eg. We can meet there, i.e. at the restaurant.
She said she was busy on Saturday night, meaning she wasn’t going to come.
