zero in on
Meaning
To focus attention very precisely on a specific person, issue, detail, or target; to identify the exact point to address.
Origin
Originally tied to aiming: to “zero in” a gun or sight means adjusting it so shots hit the target at a set distance (“zero”). By extension it came to mean narrowing in precisely on a target or point.
Notes
Suggests a tight, precise focus—often for analysis, problem‑solving, or targeting. Used in casual and business contexts. With people, it can imply scrutiny or pursuit.
