Clarify and hand over actions in English

"Hand over" means to give something you're holding or responsible for -- an object, control, responsibility, or authority -- directly to a specific other person, who becomes the one in charge of or responsible for it. The phrase itself doesn't say whether the transfer was welcome or forced; a planned, voluntary handover and a compelled one both use the same phrase.

“Can I hand over the callback to you, and can you confirm you'll take it?”

Usage note: Make the action and acceptance of responsibility explicit.

Use clarify to make information, meaning, expectations, or a position clearer and easier to understand, often by adding detail or removing ambiguity.

“Could you clarify whether you mean now or after the confirmation?”

Usage note: Do not select an action from an ambiguous instruction by guessing.

Escalate means either deliberately sending an issue to someone with more authority or expertise to resolve it, or a conflict, tension, or cost becoming more serious — and the sentence's construction, not the topic, tells you which one is meant.

“I've escalated the concern to the service lead for review.”

Usage note: Referral for review is not evidence that the concern is resolved.
