Assento vs. lugar
The Portuguese words assento and lugar can both refer to a seat in the sense of a place to sit, but they are used in different contexts. Understanding these contexts is key to using them correctly.
Assento
A2Assento specifically refers to the physical, designated area for sitting. It often has a more formal or tangible connotation, such as a chair, stool, or a numbered seat in public or professional spaces.
O assento do ônibus está ocupado.
(The bus seat is occupied.)
Verifique o número do seu assento antes de embarcar no avião.
(Check your seat number before boarding the plane.)
Esse assento está quebrado e não pode ser usado.
(That seat is broken and cannot be used.)
Lugar
A1Lugar is a broader term that refers to a place in general, which can include a physical location or an abstract space, such as your position or role. When referring to a seat, it implies the general spot where someone can sit, but not the physical seat itself.
Você pode guardar meu lugar na fila?
(Can you save my place in line?)
Apenas sente-se em qualquer lugar disponível.
(Just sit anywhere available.)

(He looked for a comfortable place to rest.)

(This is a good spot for us to have a picnic.)
Summary
The word assento refers to the specific physical object meant for sitting, while lugar has a broader meaning, denoting any location or position, including a general spot one can occupy. While both may describe a seat, assento is more precise, and lugar is more abstract and versatile.
