Extract

No Merriam-Webster or Dictionary.com entry exists, each directly checked (404) rather than reported via WebSearch synthesis, per this project's standing verification practice.
English Wiktionary does carry a genuine English-language entry (see wiktionary-mamihlapinatapai.md) — so, like lagom and gezellig, this word shows a mixed adoption pattern (one major reference work in, others out) rather than meraki's or ya'aburnee's total-absence pattern.
Collins remains blocked (403) rather than confirmed absent, consistent with this project's standing fence on that site.
OED and Oxford Learner's were not attempted this session (see Gaps) — try the r.jina.ai-proxy method per the standing note.
