Mmm

Mmm is a three-letter sequence used in language and communication to express sensory experience, consideration, or emphasis. When written as mmm, it typically functions as an onomatopoeic interjection signaling pleasure or savoring, or as a marker of thoughtful deliberation in text. Variants include Mmm, MMMMM, or all caps MMM, depending on style and emphasis.

As an acronym, MMM stands for multiple terms across fields; the exact meaning is context-dependent. The most widely known usage is the Russian financial pyramid scheme Mavrodi Mondial Moneybox (MMM), founded by Sergei Mavrodi in 1989. The scheme drew large numbers of participants across the Soviet Union and Russia, offered high returns, and collapsed in the early 1990s, with lasting impact on public perception of investment schemes. It has appeared again in later revivals or regional variants under the same initials, often facing regulatory action.

In addition to this, MMM appears in branding and organizational initials in various domains, and as an abbreviation in academic, governmental, and corporate names. Because MMM's meaning is highly context-sensitive, it is necessary to rely on surrounding text to determine whether it is an interjection, a specific organization, or another term.
