The sentence glue
In Japanese, は (wa) marks the topic and です (desu) politely closes the sentence: 'Watashi wa gakusei desu' — I am a student. These particles are the glue holding a simple sentence together.
Marking the topic
Japanese uses small words called particles to show a word's role. The particle は (written like 'ha' but pronounced 'wa' here) marks the topic — what the sentence is about. 'Desu' is a polite way to end a statement, roughly 'is/am/are'. The pattern [Topic] は [description] です builds countless sentences.
Kore wa hon desu. → 'This is a book.' Nihongo wa omoshiroi desu. → 'Japanese is interesting.'
Lab · Build a sentence
- Choose a topic word (e.g., 'neko' = cat).
- Add は after it to mark it as the topic.
- Add a description and end with です.
What you should see: 'Neko wa kawaii desu' — 'The cat is cute.' The frame [topic] は [description] です produces a polite, complete statement.
