荷物

How it works

The verb is in its て (te-form) form and then doubled — 見てて(みてて) (keep watching) is a casual squeeze of 見ていて(みていて) (be watching), meaning “keep an eye on it for a moment.” The object 荷物(にもつ) (luggage) sits bare because the object particle を (object) is dropped in relaxed speech. The final ね (right?) softens the request into a friendly “okay?” rather than an order.
