Look into
The detective’s phrasal verb: investigate, research, dig deeper. The investigate vs consider senses, why it commits you to effort (not a result), question-word patterns, the look-at → look-into → dig-into depth ladder, and a quiz.
Overview
Look into is the detective’s phrasal verb: to investigate, research, dig a little deeper. Not a quick glance — a small investigation.
- Investigate / research → investigate, examine, research, explore
- Consider / explore an option → consider, explore the possibility
“I’ll fix it” = a promise. “I’ll look into it” = “I’ll investigate and come back to you” — perfect when the cause is still unknown.
Parts of speech
Look into is a verb only — there’s no noun “a lookinto.” The noun idea is carried by an investigation or a review.

- check — verify something specific: “Check the logs.”

- look into — investigate, get to the cause: “Look into the memory leak.”

Register & mnemonic
Register: neutral-professional, appropriate everywhere. Formal synonym: investigate (“We are investigating the incident” — an official postmortem) or examine. In live communication look into sounds more natural.
look at = you look at the box; look into = you open it and examine what’s inside. 🔍

3.“We need to ___ the legacy code to understand it fully.”
4.“Can you ___ why the tests are flaky?”
5.“Just ___ the screenshot I sent.”
