Questions & Answers about shuumatsu ni kazoku to ryokoukeikaku o kimemasu.

Why is に used after 週末?

In Japanese, に marks a specific point in time. Attaching に to 週末 indicates “on the weekend.” Without に, it would sound incomplete when indicating when something happens.

What does と mean in 家族と?

The particle と here means “together with” or “and.” 家族と literally means “with (my) family.”

Why is there を before 決めます?

The particle を marks the direct object of the verb. Here, 旅行計画 (travel plan) is what you are deciding, so it takes を.

What is 旅行計画, and why are two nouns combined?

旅行計画 is a compound noun: 旅行 means “travel” and 計画 means “plan.” Combined, it forms “travel plan.” Japanese often stacks nouns to create a more specific concept.

What is the dictionary form of 決めます, and what nuance does it carry?

The dictionary (plain) form is 決める. It means “to decide” or “to settle on.” The ～ます form (決めます) is the polite present tense, so it’s “(I) decide” or “(I) will decide.”
