Are you doing something?
Or is something being done to you?
This is the starting point for deciding the subject or object of a sentence.
This is the person doing the action. The subject usually comes before the verb in a sentence:
The subjects in these sentences are Adam, Jane and Lucy. They are doing the action (verb): to swim, to write, to work.
This is the person, place or thing that is impacted by or involved in the action:
Adam swims at the local swimming pool.
Jane writes in her diary every evening.
Lucy works at the supermarket.
The objects in these sentences are the local swimming pool, Jane's diary and the supermarket.
Let's identify the subject and object in each of the following sentences:
Ben plays hockey on Tuesdays. subject: Ben object: hockey
Helen does her homework every evening. subject: Helen object: homework
Melanie orders pizza every Friday evening. subject: Melanie object: pizza
Liam visits his grandparents once a month. subject: Liam object: his grandparents
If you are not sure how to identify the object, try asking a 'what' question about the subject:
Colin ate ice-cream on holiday.
What did Colin eat? - ice-cream. This tells us that 'ice-cream' is the object.
Emma is a teacher.
What is Emma? - a teacher. This tells us that 'a teacher' is the object.
Olive drives her car to work every day.
What does Olive drive? - her car. This tells us that 'her car' is the object.
Richard invented a robotic dog.
What did Richard invent? - a robotic dog. This tells us that 'a robotic dog' is the object.
