Questions & Answers about watashi wa douryou o shinraishite imasu.

Why is は used after 私?

は marks 私 as the topic of the sentence. It sets up what the sentence is about: as for me...

So 私は does not simply mean I in a neutral grammatical sense; it gives a topic-comment structure:

• 私は = As for me
• 同僚を信頼しています = trust my coworker / trust my coworkers

In many beginner sentences, は is translated as part of the subject, but its actual job is to mark the topic.

Could 私 be omitted?

Yes. Very often, Japanese leaves out subjects and topics when they are clear from context.

So in a normal conversation, people might simply say:

• 同僚を信頼しています。

That can still mean I trust my coworker / coworkers, depending on the situation.

Including 私 can make the sentence clearer, more contrastive, or slightly more explicit than Japanese usually needs.
