"十二个月用英语怎么说"在英语中是 "How to say twelve months in English".
If you want to ask how to spell it, it's spelled as T-H-E-E-V-E-N.
If you want to ask about the pronunciation, it's pronounced as "TWELVE MEE-NUHS".
If you want to ask about the plural form, it's still twelve months, but with an "s" at the end: TWELFY MEE-NUHS.
I hope that helps! Let me know if you have any other questions.
