Questions & Answers about nimotsu ga omosugite, hitori de wa hakobemasen.

What does 重すぎて mean and how is すぎる used with adjectives?

すぎる attached to an adjective indicates “too …” or “excessively …”. With い-adjectives, you drop the final い and add すぎる.

• 重い → 重
  • すぎる = 重すぎる (“too heavy”)
• Then the て-form of 重すぎる is 重すぎて, used here to link clauses.

Why is the て-form (as in 重すぎて,) used instead of ので or から?

The て-form here expresses a cause–result relationship in a neutral or conversational style:
“(Because it’s too heavy,) I can’t carry it alone.”
You could also say:

• 荷物が重すぎるので、一人では運べません。
• 荷物が重すぎるから、一人では運べません。
  But 重すぎて is more direct and common in spoken Japanese.

What’s the function of は in 一人では運べません? How is it different from just 一人で?

一人で means “by oneself.” Adding は—一人では—marks that entire phrase as the topic or point of contrast:
“As for doing it alone, (it) can’t be done.”
It emphasizes that, at least when you’re alone, carrying it is impossible.

Why is it 運べません instead of 運びません?
