Notes & Nuances

📌 Important Points

Emphasis on Addition
に加えて emphasizes that the second element is an extra, often significant, component added to the first. It often implies that the second element further strengthens or complicates the situation presented by the first.
Example: 忙しさに加えて、体調も崩してしまった。(Isogashisa ni kuwaete, taichō mo kuzushite shimatta.) – In addition to being busy, I also fell ill. (Emphasizes the added burden of illness.)
Primarily with Nouns
While theoretically usable with other word classes, に加えて is most naturally and commonly used following a noun. When using with verbs or adjectives, they are usually nominalized with の or なの.
Example: 彼の仕事の速さに加えて、正確さも評価されている。(Kare no shigoto no hayasa ni kuwaete, seikakusa mo hyōka sarete iru.) – In addition to the speed of his work, his accuracy is also praised.

⚠️ Common Mistakes

❌ Incorrectly attaching to plain forms of verbs/adjectives without の/なの
✅ 彼は泳ぐに加えて、走ることもできる。 (Incorrect) 彼は泳ぐのに加えて、走ることもできる。 (Correct)
When attaching に加えて to plain forms of verbs or adjectives, they need to be nominalized with の or なの to function as nouns before に加えて.
❌ undefined
✅ undefined

🏛️ Cultural Context

Politeness Level: Neutral to slightly formal. It is appropriate for most situations where you need to clearly state additional information.
Social Situations: Suitable for business meetings, academic discussions, news reports, and formal explanations. It can be used in personal conversations for clarity or emphasis, but casual conversation might prefer simpler conjunctions.
Regional Variations: No significant regional variations in its usage or meaning.

🔍 Subtle Differences

〜に加えて vs. 〜だけでなく〜も
「に加えて」 emphasizes the *addition* of one element to another, often implying an accumulation or compounding effect. 「〜だけでなく〜も」 (not only X, but also Y) focuses on the idea that both X and Y exist, emphasizing the breadth rather than just the addition.
When to use: Use 「に加えて」 when you want to highlight the extra element as an augmentation or a further factor. Use 「〜だけでなく〜も」 when you want to state that something has multiple attributes or applies to multiple things.
〜に加えて vs. 〜上に (ue ni)
Both mean “in addition to.” 「に加えて」 is more general for adding another item or fact. 「上に」 often implies that the second element *builds upon* the first, often in a logical or sequential way, or adds a further positive/negative aspect to an existing one.
When to use: Use 「に加えて」 for general addition. Use 「上に」 when the second item logically follows or reinforces the first, often with implications of “on top of that” or “what’s more.” For example, 「安い上に美味しい」(cheap, and what’s more, delicious).
〜に加えて vs. その上 (sono ue)
「に加えて」 directly links the additional information to a preceding noun or clause. 「その上」 is a conjunctive phrase used to introduce an additional point or reason, often at the beginning of a sentence or clause, acting more like “furthermore” or “moreover.”
When to use: Use 「に加えて」 to attach directly. Use 「その上」 to introduce a new, additional statement.

📝 Conjugation Notes

When used with verbs or adjectives, they must be nominalized: Verb plain form + のに加えて い-adjective + のに加えて な-adjective stem + なのに加えて Example: 勉強するのに加えて (in addition to studying) 高いのに加えて (in addition to being expensive) 便利なのに加えて (in addition to being convenient)

🔊 Pronunciation Tips

「に加えて」 (ni kuwaete) is pronounced with a relatively flat intonation, with a slight rise on 「く」 (ku). The 「に」 (ni) particle is pronounced short and sharp. Pay attention to the double consonant in 「加えて」 (kakuwaete) for a clear pronunciation.

🧠 Memory Tips

Think of it as “plus” or “adding to the list.” Visualize adding an item to a basket: “This item, plus this one.” The kanji for 加える (kuwaeru) means “to add.”
