What does esse mean?
Esse is the Latin word for 'to be', adopted into English chiefly as a noun of philosophical weight. In metaphysics, particularly the scholastic tradition of Aquinas, it names the sheer act of existing — being itself — as opposed to essence, which is what a thing is. This contrast between esse and essence lies at the heart of classical arguments about creation, where God alone is said to be whose essence simply is his esse. Beyond technical theology, the word survives in a handful of learned phrases: 'esse quam videri' ('to be rather than to seem'), adopted as North Carolina's state motto, and 'in esse', meaning actually existing rather than merely potential. Formal and rare in everyday use, esse nonetheless offers writers a precise term for existence at its most fundamental, carrying connotations of depth, authenticity, and substance that plainer words like 'being' do not always convey.
nounIn philosophy, the essential nature or actual existence of something; the Latin word for 'being', used especially in scholastic and metaphysical contexts to denote pure existence as distinct from what a thing is.
- Pure existence or act of being, especially in scholastic philosophy.
- The essential nature or substance of a thing.
"For Aquinas, God's essence and esse are identical, whereas every created thing merely participates in being."
"Medieval philosophers debated whether esse could ever exist apart from essence."
"Her writing was praised for its concern with esse over appearance — substance rather than show."
Rarely pluralized; the plural occurs only in technical discussions comparing different acts or modes of being.
"The treatise distinguished between several distinct esses within the hierarchy of beings."
'Esse quam videri' — 'to be rather than to seem' — is North Carolina's state motto, borrowed straight from Latin for one of philosophy's most loaded little words.

Etymology of esse
Esse is the infinitive of the Latin verb 'to be', one of the most ancient verbs in the Indo-European family, descending from Proto-Indo-European *h₁es-. Its derivatives saturate both Latin and English: essence, essential, presence, absence, and entity all trace back through forms built on this root. The word entered English scholarly usage in the medieval period through scholastic philosophy, where it was retained untranslated because its technical sense resisted neat translation into vernacular terms.
How esse is actually used
Highly formal and technical, confined largely to philosophy, theology, and academic prose. Outside those registers it appears mainly in fixed Latin phrases such as 'esse quam videri' or 'in esse'. Italicization is conventional when used as a foreign term in English text.
Easily confused with esse
Esse denotes the act or fact of existing (being itself), while essence denotes the defining nature or qualities that make a thing what it is.
