The Latin verb esse — Classical languages, 11–13 years
Esse means “to be”. It is a small but unusual verb that connects people and things with what they are, where they are, or how they seem.
Esse means “to be”
The Latin word esse is the dictionary form of “to be”. Its forms include sum, “I am”, est, “he, she, or it is”, and sunt, “they are”. Latin can leave out a subject pronoun because the verb form already gives useful information about who is being described.
Why learn this small verb?
Every language needs a way to say that something exists, has an identity, or is in a state. Latin uses esse for all these jobs, so it appears constantly in simple sentences and inscriptions. It is irregular because very common words tend to preserve old forms instead of following a neat pattern.
Building a sentence with sum
Start with puella, “the girl”, and laeta, “happy”. Add sum, “I am”: puella laeta sum means “I am a happy girl”. The word puella appears first, but sum tells us the speaker is “I”; Latin can make that clear without writing ego. The adjective laeta matches puella because it describes her.
Do not translate every form as “is”
A reasonable mistake is to remember only est and use it for every subject. English often keeps “is” visible, so this shortcut feels natural. Check the Latin form instead: sum means “I am”, es means “you are”, est means “he, she, or it is”, and sumus means “we are”.
A key to short Latin texts
Forms of esse appear in mottos, inscriptions, stories, and scientific names based on Latin. If you recognise est or sunt, you can often spot the part that says what something is or where it stands. The same verb also helps with phrases such as carpe diem’s implied “seize the day”, though not every famous phrase uses esse.
