Comma with Filler Words (You Know, I Mean, Like, Okay, See)
The Comma
Rulebase Summary
Use commas to set off filler words and expressions that speakers use to fill gaps when they are unsure, seeking approval, or speaking habitually. Common fillers include 'you know,' 'you understand,' 'I mean,' 'okay,' 'see,' 'say,' and 'like.' However, when 'like' is used as a synonym for 'about' or 'around' (approximation), it is not a filler and should not be set off with commas.
