Ser vs. Estar

Ser vs. Estar — Permanente vs. Temporário

💡

Key Concept

English uses 'To Be' for everything. Portuguese splits 'To Be' into two completely different verbs based on time. Ser is for permanence (the essence); Estar is for temporary states (the current condition).
粵

Cantonese Speaker Tip

最難唄部分！ 廣東話將「係」一個字搞定，但葡文分兩個：

Ser = 永久/本質的「係」——「我係葡萄牙人」(Sou português)
Estar = 臨時/狀態的「係」——「我而家係度很累」(Estou cansado)

記住：如果唄野唔會變（國籍、職業、性格）用 ser， 會變唄（心情、健康、位置）用 estar。

Ser defines WHAT something IS — identity, origin, profession, physical traits, character. Estar describes HOW something IS right now — mood, health, location of movable objects. The same adjective can be used with both verbs, changing the meaning entirely.

Key Phrase — Try saying it!

Ela é faladora, mas hoje está calada.
