更に【さらに】

更に (さらに) is an adverb meaning "furthermore," "moreover," "even more," or "in addition." It is used to indicate that something goes beyond a current level or that additional information is being added. It functions similarly to English expressions like "on top of that," "what's more," or "still more."

Adding degree – "even more"

更に can intensify an adjective, verb, or state, expressing that something increases or goes beyond its current level.

In this usage, 更に functions like もっと but carries a more formal or literary tone. While もっと is common in everyday conversation, 更に is preferred in writing, presentations, and formal speech.

Adding information – "furthermore / moreover"

更に can also connect ideas, introducing additional information on top of what has already been stated. This usage is common in essays, news, and speeches.

Escalating situations – "more and more"

更に can describe situations that continue to escalate or develop.

Notes

• 更に is more formal than もっと. In casual conversation, もっと is more natural.

• When connecting sentences, 更に often appears at the beginning of the second sentence, sometimes followed by a comma: さらに更に、〜～.

• It can modify verbs, adjectives, and even entire clauses.
