Learners often make two grammar mistakes with flag, and both come from the same pattern.
First, they put the person before the issue by saying "flag Priya about the risk" instead of "flag the risk to Priya." Second, they add an unneeded "about" before the object, as in "flag about the delay" instead of "flag the delay."
The object is the issue, not the person
In the standard workplace pattern, the object of "flag" is the issue, and the recipient follows after "to." People often treat "flag" like "talk to someone about something," which creates both mistakes.
Wrong: "I flagged my manager about the delay." Right: "I flagged the delay to my manager."
Wrong: "She flagged about a data-quality issue in the report." Right: "She flagged a data-quality issue in the report."
One important exception is worth knowing. "Flag someone" can be correct when that person or account is marked for review. This is a different, narrower use; it does not simply mean "notify someone."
Exception, not an error: "The account was flagged for unusual login activity" -- here the account itself is the item being marked, which is different from "notify the account holder."

Both mistakes copy verbs like "tell" or "talk to," where the person comes first and the topic may follow with "about." The usual pattern for flag is different: put the issue first and the person after "to."
A quick test before you send the sentence
Check what comes right after the word "flag." A person's name may signal the reversed-object mistake, except when that person or account is being marked. If the next word is "about," you can usually delete it.
People will usually understand these sentences, but a careful editor may still correct them.
Use "to" before the recipient, and do not put "about" before the object. These two reliable habits prevent both common errors.
Practice scenarios
Practice using flag in these situations.
- correcting a sentence that puts the person before the issue
- double-checking whether 'about' belongs in a flag sentence at all
- recognizing the one case where 'flag someone' is actually correct
Useful practice phrases to try.
- "I flagged the delay to my manager."
- "She flagged a data-quality issue in the report."
- "The account was flagged for unusual login activity."
Use this object rule: the "issue" goes first, and the "recipient" follows with "to."
That one change fixes two common grammar errors with this word.
