Questions & Answers about shashin ga oosugite, daunroodo mo appuroodo mo jikan ga kakarimashita.

Why is it 多すぎて instead of just 多くて?

多すぎて means being too many or because there were too many.

It is built from:

• 多い = many / a lot
• すぎる = to exceed / too much
• て = connects to the next clause

So:

• 写真が多い = there are many photos
• 写真が多すぎる = there are too many photos
• 写真が多すぎて、... = because there were too many photos, ...

If you said 多くて, it would mean there were many, and... but it would not have the strong idea of too many.

Why is が used after 写真?

In 写真が多い, the noun counted or described by 多い is commonly marked with が.

So:

• 写真が多い = there are many photos
• literally, photos are many

This is a very normal pattern in Japanese. A learner may expect 写真を somewhere, but 多い is an adjective, not an action done to the photos, so が makes sense here.

What exactly is the role of て in 多すぎて?

Here, て connects the first idea to the second idea and gives a reason/cause feeling.

So the sentence structure is basically:

• 写真が多すぎて = because there were too many photos
• ダウンロードもアップロードも時間がかかりました = both downloading and uploading took time

The て-form does not always mean cause, but in this sentence that is the most natural interpretation.
