“Seles” can mean a few different things depending on context, so here’s the quick scoop.

Fast answer

  • In many cases online, “Seles” refers to Monica Seles, a famous former world‑number‑one tennis player with nine Grand Slam singles titles.
  • “Seles” is also used as a given name meaning “moon”, likely derived from the Greek “Selene”.
  • As a word form, “seles” appears in older/other languages (like Old French, Portuguese, Spanish) as a grammatical form of other words, not a standalone modern English term.
  • There is at least one company called SELES involved in export / internationalization services for Italian businesses.

If you meant a specific “Seles” (a person, a game, a company, a language form), the meaning shifts a bit.

Main meanings of “Seles”

1. Monica Seles (the person)

When people say “Seles” in a sports or news context, they almost always mean Monica Seles.

  • She is a retired professional tennis player who represented Yugoslavia and later the United States and reached world No. 1 in women’s singles.
  • She won nine Grand Slam singles titles and was one of the dominant players of the early 1990s.

So if you see headlines or forum posts like “Is Seles the most underrated champion?”, they’re talking about Monica Seles.

2. “Seles” as a name

“Seles” also appears as a first name.

  • One baby‑name source describes Seles as a unisex name pronounced “SEH‑less,” meaning “moon,” and says it likely comes from the Greek root “selene,” which also means “moon”.

People might ask “what is Seles” in name forums when they’re checking meaning, origin, or pronunciation.

3. “seles” as a word form

In dictionary/linguistics contexts, “seles” is not a common modern English word; it mainly shows up as an inflected form in other languages.

  • A multilingual dictionary lists “seles” under Old English, Old French, Portuguese, and Spanish as a form related to other base words (for example, as an inflected form connected to the Spanish verb “ser” combined with the pronoun “les”).

So if you saw “seles” in a historical text or grammar explanation, it may just be a plural or imperative form, not a standalone concept.

4. SELES as a company/brand

In a business or LinkedIn context, SELES can be a brand name.

  • One example is SELES, a division of an Italian firm (Everap Spa), which focuses on internationalization and temporary export management for Italian companies, operating since the 1980s.

In that setting, “what is Seles?” would be “what does this company do?”

Which “Seles” do you mean?

Because “what is seles” is short, people might be referring to:

  • The tennis legend Monica Seles (sports talk, history, news)
  • The given name Seles (baby‑name or astrology-style sites)
  • A grammar form in another language (linguistics / translation)
  • The SELES business brand (LinkedIn, B2B sites)

If you tell me the context (sports, names, language, business, or something else like anime/game or forum meme), I can narrow it down and give a more targeted explanation. TL;DR:
Most commonly, “Seles” = Monica Seles, the tennis star; it can also be a moon‑related given name, a grammatical word form in other languages, or a company name, depending on where you saw it.
