IPA: /ædˈvɜːrtəntli/
KK: /ædˈvɜrtəntli/
In a way that is done intentionally or on purpose, rather than by accident.
She inadvertently revealed the surprise party, but he had planned it advertently.
Advertently → It is formed from "ad-" (meaning to) and "vertere" (meaning to turn). The word describes the act of turning one's attention to something intentionally or knowingly.
Think of 'turning' your attention 'to' something — that's why advertently means doing something intentionally.
