Piggyback
To add onto someone's point, as in 'just to piggyback on that.' The meeting's most popular verb for agreeing while ensuring your voice is also in the minutes.
Heard in the wild
“Just to piggyback on Maria's point — the vendor issue affects us too.”
Tone check: Cliché
Fine occasionally. Serial piggybackers add mileage, not content — don't become one.
