Grammar Rule in 30 Seconds
In Thai, you can drop the subject or object if it's already clear from the conversation context.
- If the person is known, drop the pronoun: 'กินข้าวหรือยัง' (Have [you] eaten?)
- If the object is clear, omit it: 'ซื้อมาแล้ว' ([I] bought [it] already).
- Use pronouns only for emphasis or when introducing a new topic.
Overview
Meanings
The practice of omitting pronouns (I, you, he, she, it) when the context makes the subject or object obvious to the listener.
Subject Omission
Dropping the person performing the action.
