"Chip away at" has a shape learners often memorize before they check whether it actually fits the noun that follows — and that's where a technically well-formed sentence can still read as nonsensical, or unintentionally funny.
The actual test: can it gradually shrink or weaken?
Natural business objects for "chip away at" are things that can be gradually reduced, weakened, or worked down over time. That covers a wide range of abstract resources and conditions: margins, trust, technical debt, market share, resistance, customer confidence. What doesn't fit are physical, one-off items — things that don't have a "gradually weakening" state to begin with.
Natural: "chip away at our market share" — market share is a value that can shrink gradually over time, a little at a time, as competitors win individual customers or deals.
Natural: "chip away at customer confidence" — confidence is a condition that can weaken through repeated small issues, none individually decisive.
Implausible: "chip away at a colleague's laptop charger" — a laptop charger is a fixed physical object, not something gradually reduced or weakened over time. It doesn't fit the metaphor's target domain at all.
Why the physical-object version fails
The mistake here isn't a grammar error — "chip away at a colleague's laptop charger" is a perfectly well-formed sentence structurally. The problem is that a laptop charger doesn't have a state that "chip away at" can meaningfully describe. It's not a resource, a condition, or a quantity that gradually shrinks or weakens; it's a fixed physical object that either works or doesn't. There's no gradual, partial version of "chipped-away" a charger.

Start learning for free →That's the real test to run before using the phrase: not "is this a noun," but "does this noun name something that has a gradually-reducible state" — a level, a quantity, a condition, a value that can meaningfully be described as partially eroded or partially reduced.
Quick self-check list
Run through a few more examples to calibrate the pattern. Margins, budgets, and market share all work because they're quantities that can shrink incrementally. Trust, confidence, credibility, and morale all work because they're conditions that can weaken gradually, in degrees. Technical debt and a backlog work because they're accumulated burdens that can be reduced piece by piece. A specific physical object — a laptop, a charger, yesterday's meeting notes, a stapler — doesn't work, because none of those have a partial, in-between state that "chipping away" could plausibly describe.
Why this matters beyond the quiz format
The mistake is memorizing the phrase's shape without checking whether the following noun can actually be gradually reduced or weakened. If the object is a specific physical item rather than an abstract resource, condition, or quantity, "chip away at" doesn't fit — and the sentence reads as nonsensical or unintentionally comic rather than merely informal. Running the quick mental check — does this noun have a state that can gradually shrink or weaken? — before you commit to the phrase is enough to avoid the mistake entirely.
Practice scenarios
Practice using chip away at in situations like:
- checking whether a noun actually fits before committing to chip away at
- explaining why chip away at a physical object sounds wrong even though it's grammatical
- building a mental list of the kinds of nouns that do and don't fit
- catching an unintentionally comic sentence before it goes out
Useful practice phrases:
- "Does [noun] actually have a state that can gradually shrink or weaken?"
- "We're chipping away at [market share/trust/technical debt] — that fits."
- "That's a physical object, not something that gradually erodes."
- "Let's run the quick check before we commit to this phrase."
The shape of the phrase is easy to memorize; the fit with the noun is what takes judgment.
Ask whether the object can gradually shrink or weaken before you write the sentence.
