IPA: /kənˈsɜːrtɪdli/
KK: /kənˈsɜrtɪdli/
In a way that is planned and done together by a group of people.
The team worked concertedly to finish the project on time.
Concertedly → It is formed from "con-" (meaning together) and "certus" (from Latin, meaning certain or fixed) and the suffix "-ly" (meaning in a manner). The word "concertedly" means in a manner that is done together or in agreement.
Think of people acting 'together' ('con-') in a 'certain' way ('certus') — that's why concertedly means doing something in agreement.
