Questions & Answers about juudenkeeburu o wasureta node, sumaho no juuden ga dekimasen.

Are the spaces normal in Japanese?

No. In normal Japanese writing, this would usually be written without spaces:

充電ケーブルを忘れたので、スマホの充電ができません。

Spaces are often added in textbooks or beginner materials to make the sentence easier to read.

Why is there no subject like I in the sentence?

Japanese often leaves out information that is obvious from context.

So this sentence does not explicitly say I forgot the charging cable, but that is the natural understanding in many situations.

A fuller version could be:

私は充電ケーブルを忘れたので、スマホの充電ができません。

But in everyday Japanese, 私は is often omitted because it is already understood.

Why is を used after 充電ケーブル?

を marks the direct object of the verb.

The verb 忘れる means to forget, and the thing you forget takes を:

• 鍵を忘れた = I forgot my keys
• 財布を忘れた = I forgot my wallet
• 充電ケーブルを忘れた = I forgot the charging cable

So 充電ケーブル is the thing that was forgotten.

Why is 忘れた in the past tense?
