Describes what something permanently is, its essence
Encoding Strategies:

Ser means to be and refers to what something fundamentally is0. The English word "is" is a cognate of its third-person form "es", which English turns into a noun in the word "essence" (es + -ence): something's permanent, inherent nature. That's exactly what ser describes.
ser
to be (traits)
Physical and personality traits are permanent, fundamental properties of what something is.
- Es alta y tiene el pelo negro = She is tall and has dark hair
to be (profession)
Historically, your profession defined who you were, not what you temporarily do. People were even named after their trade (e.g. Baker and Smith are common last names). Spanish preserves that idea: a doctor doesn't just do medicine, they are a doctor.
- Soy médico = I am a doctor
to be from, to be (origin / nationality)
Origin and nationality are permanent facts about what someone is.
- Somos españoles = We are Spanish
- Soy de México = I am from Mexico
to be (time)
Used to identify what time something is. This best thought about using the "to exist" sense of is - like there "is" a solution to this problem, a solution exists. Existence is the most fundamental, permanent property of anything.
- Son las tres de la tarde = It is three in the afternoon (three o'clock in the afternoon exists now)
- La reunión es a las tres = The meeting is at three (the meeting exists at three)
to be, to take place (location of events)
An event is defined by where it takes place — the concert doesn't happen to be at the venue the way a person happens to be standing somewhere. The venue is part of what the event fundamentally is.
- La boda fue en la iglesia = The wedding was at the church
- ¿Dónde es el concierto? = Where is the concert?
being, creature (noun)
Ser also doubles as a noun meaning literally 'a thing that is, a thing that exists.' The act of existing is the most permanent, fundamental thing possible.
- Los seres humanos somos animales sociales = Human beings are social animals
- Había seres extraños en el bosque = There were strange creatures in the forest
ser de
to be, to belong to (possession)
Historically, property was considered a permanent extension of the owner, meaning an object's identity was inseparable from who held it. Spanish preserves this by treating possession as an inherent quality of the object, defining what it is by whose it is.
- Este coche es de mi hermano = This car is my brother's
to be made of (material)
What something is made of is literally its essence.
- La mesa es de madera = The table is made of wood
ser para
to be for, to be used for
Para expresses a purpose or goal, and when combined with ser, it defines a thing's purpose as part of its essence.
- Los cuchillos son para cortar, no para jugar = Knives are for cutting, not for playing
