To say "what is the English for this" in English, you can say "What is the translation for this?" or "What is the equivalent in English for this?"

The phrase "what is the English for this" comes from the idea of translating words or phrases from one language to another. In this case, the speaker is asking for the English equivalent of a word or phrase in another language.

Here are some example sentences using this phrase:

"What is the English for '你好'?" (What is the translation for "你好"?)

"Can you tell me what the English is for 'merci beaucoup'?" (Can you tell me the equivalent in English for "merci beaucoup"?)

"I'm trying to learn Spanish, but I'm not sure what the English for this word is." (I'm trying to learn Spanish, but I'm not sure what the translation for this word is.)
