に加えて
In Addition to
に加えて is a formal way to say 'in addition to.' It is used when you want to add a new piece of information (B) to an existing one (A) to show a cumulative effect (A + B).
How It Works
に加えて comes from the verb 加える（くわえる）. It functions as a compound particle to link two nouns or nominalized phrases that belong to the same logical category.
1. Formation:
- Noun + に加えて: 英語に加えて (In addition to English...)
- Verb + ことに加えて / のに加えて: 食べることに加えて (In addition to eating...)
- い-adjective + ことに加えて: 安いことに加えて (In addition to being cheap...)
- な-adjective + なことに加えて: 綺麗なことに加えて (In addition to being beautiful...)
2. Nuance and Register:
This pattern is formal. In casual conversation, speakers usually use それに or も. In literary or highly formal writing, the て is often dropped to become に加え. Note that に加え is still a particle and must follow a noun; it cannot start a sentence on its own.
3. Sentence Structure:
To sound natural, the second part of the sentence must typically include additive particles like も (also), まで (even), or さえ (even) to reinforce the connection between the two items.
4. Semantic Constraint:
This expression is used to link items that are logically related or fall under the same theme (e.g., two different skills, two different problems, or two different weather conditions).

In addition to the strong winds, the rain has also become severe.
Word by Word: Violent wind to adding, rain also severe became.
Here, 'rain' is added to the already existing 'wind' to describe a worsening situation. Note the use of も in the second clause to complete the additive logic.

When adding a state or action, the verb/adjective must be nominalized using こと or の before adding に加えて.

Common Mistakes
Attaching directly to a verb without nominalization.
食べるに加えて、飲むのも好きだ。食べることに加えて、飲むのも好きだ。に加えて must follow a noun. To use it with a verb, you must add こと to turn the verb into a noun phrase.
Using it in very casual daily conversation.
ピザに加えて、パスタも食べたい！ピザと、あとパスタも食べたい！While grammatically correct, に加えて sounds too stiff for a casual lunch with friends. Use と or それに instead.
