Escalate and aggravate are close enough in meaning to swap by accident, but they aren't the same move. "Escalate" is the standard term for a conflict or situation rising in severity in everyday business register; "aggravate" skews toward a more academic or formal-written register, typically used for worsening an already-bad condition. The idea overlaps, but the register doesn't -- one of these two words can sound noticeably overdressed in a routine status update.
The distinction
The underlying idea overlaps -- both can describe making something worse -- but the register and the typical object don't. "Aggravate" shows up more in formal reports or careful written analysis, and it tends to modify an existing bad condition (aggravating an injury, aggravating a shortage) rather than describing a conflict between people in plain business terms.
Using it in a routine status update or Slack message can read as overly formal where "escalate" would sound more natural.
In practice
Formal/academic register, existing condition: "The extended outage aggravated an already strained relationship with the client."
Standard business register: "The missed SLA escalated into a formal contract review with the client's legal team."
Notice what changes between the two: it isn't the tone or the formality of the sentence, it's the actual claim being made about who now owns what happens next.

Register mistakes like this one are easy to make and easy for a native reader to notice. "Aggravate" in a quick Slack update about a disagreement between two colleagues can read as unintentionally stiff or overly formal -- the kind of word choice that draws attention to itself instead of to the actual update. Saving it for formal written analysis, and reaching for "escalate" in routine business writing, keeps the register matched to the document.
The test
If you're writing a routine status update or Slack message about a conflict between people, "escalate" is almost always the more natural choice. Save "aggravate" for more formal written analysis, or for describing an already-bad condition getting worse rather than a conflict.
Try it yourself
A fast way to internalize the distinction is to take a real sentence from your own work and rewrite it twice -- once with escalate, once with aggravate -- and check whether the meaning genuinely changes or stays the same. If swapping the word doesn't change what a reader would understand about who now owns the next step, the sentence probably didn't need escalate in the first place. If the meaning does shift once you swap it, that shift is exactly the signal you reached for the right word the first time. Practice the escalate-vs-aggravate advanced-precision exercise in Lyra.
Escalate and aggravate aren't rivals so much as answers to different questions. Ask which question your sentence is actually answering, and the right word follows.
