Difference between “wa” and “ga”
As promise, today I will explain one of the most confusing particles faced by most Japanese Learning Students.
1. Mr. Tony eats bread. - Toni-san wa pan o tabemasu.
2. Mr. Tony eats bread. - Pan wa Toni-san ga tabemasu.
The difference of the above two sentences is that (1) is talking about “Toni-san” and (2) is about “pan (bread)”. In another words, (1) is answering a question such as “What Toni-san eats?” and (2) such as “Who eat bread?”.
Either sentence does not necessarily need a question, but the main interest is “Toni-san” in (1), and “pan” in (2). The essential difference of (1) and (2) is the topic. The topic in (1) is “Toni-san”, and “pan” in (2).
The expression “Toni-san wa…” in (1) indicates that “Toni-san” is the topic, so the speaker is talking about or making question about “Toni-san”, and this is the function of “wa”. You can let the people know that you are talking about X by saying “X wa…”, and this function is called topic marker in the field of linguistics.
In other words, “wa” is a topic marker and “ga” is a subject marker. The topic can be anything that a speaker wants to talk about (It can be an object, location or any other grammatical element). In this sense, it is similar to the English expressions, “As for ~”.
“Wa” is used to mark something that has already been introduced into the conversation, or is familiar with both a speaker and a listener. (proper nouns, genetic names etc.) “Ga” is used when a situation or happening is just noticed or newly introduced.
Another example will be the combination of “wa” and “ga” in one sentences
Mr. Tony is staying in this house. Mr. Tony is a teacher.
Toni-san ga kono ie ni sunde imasu. Toni-san wa sensei desu.
In the above example, “Toni-san” is introduced for the first time. It is the subject, not the topic. The second sentence describes about “Toni-san” that is previously mentioned. “Toni-san” is now the topic, and is marked with “wa” instead of “ga.”
Almost all future lessons will be using “wa” and “ga”. So the more you read , the more you will understand. Stay Tune !!!
