Elaborate on and unpack both come after "can you say more about that," which makes them feel interchangeable. They're asking for two different things, though: one asks for more content, the other asks for the content that's already there to be exposed.
Adding detail vs. revealing structure
"Elaborate on" asks the speaker to extend a point that's currently thin -- to add new information, examples, or reasoning that wasn't there before. "Unpack" asks the speaker to expose the parts that are already built into a claim, even if they haven't been stated yet.
Elaborate on (the point needs more content): "Can you elaborate on that? You only gave us one example, and I think there's more to it."
Unpack (the structure is already there, just not visible yet): "Can you unpack that recommendation? I want to understand what assumptions it's resting on."
A quick test
Ask yourself: is the point currently thin and in need of more material, or is it already dense and just needs its existing parts made visible? A recommendation that already reflects real analysis usually has structure worth unpacking. A one-line comment that hasn't been developed yet usually just needs elaboration.

Lyra Practice teaches advanced non-native professionals the nuance of high-value expressions like this one, then has you practice using them in realistic work scenarios.
Start learning for free →Thin point, needs elaboration: "We should prioritize retention." → "Can you elaborate on that -- what would that look like in practice?" Dense point, needs unpacking: "We should prioritize retention because the acquisition funnel is already maxed out and support tickets suggest churn is preventable." → "Can you unpack that -- which of those factors is actually driving the recommendation?"
The rule
Ask someone to "elaborate on" a point when it's underdeveloped and needs more content added. Ask them to "unpack" a point when it's already a compact, reasoned claim and you want its existing structure made visible. Using "unpack" on a genuinely thin point overstates the complexity that's actually there.
Practice scenarios
Practice choosing between unpack and elaborate on in situations like:
- deciding whether a point needs more content or just needs its structure exposed
- asking a colleague to develop a one-line comment further
- asking a colleague to expose the reasoning behind an already-dense recommendation
Useful practice phrases:
- "Can you elaborate on that? I think there's more to it."
- "Can you unpack that recommendation? What's it resting on?"
- "That's a dense point -- let's unpack what's actually driving it."
Thin point, ask them to elaborate. Dense point, ask them to unpack it.
