The correct way to write and pronounce “March 9th” in English is as follows:

Writing:

– The numeral “9” is followed by the word “th” to indicate the ordinal form of the number, which signifies the ninth day of the month.

– The word “March” is spelled with an initial capital “M” as it is the name of a month.

Pronunciation:

– The pronunciation of “March 9th” can be broken down into three parts: “March,” “9,” and “th.”

– “March” is pronounced as /mɑːrtʃ/, with the emphasis on the first syllable.

– The numeral “9” is pronounced as /naɪn/, with the emphasis on the second syllable.

– The suffix “th” is pronounced as /θ/, similar to the “th” in “think” or “this.”

So, when you put it all together, “March 9th” is pronounced as /mɑːrtʃ naɪn ðɛt/, with a slight pause between “March” and “9th.” The “th” at the end is not pronounced as in “this” or “that,” but rather as a soft, unvoiced sound.
