There are several possibilities, depending on the desired pronunciation and feel:
* 제롬 (Jerom): This is a common and straightforward transliteration, using the Korean alphabet (Hangul) to represent the sounds of the name as closely as possible. This is probably the most widely understood option.
* You could also find a Korean name with a similar meaning or sound. However, without knowing the meaning or desired "feel" of the name, suggesting alternatives would be purely speculative.
Therefore, 제롬 (Jerom) is the most practical and recommended way to write Jerome in Korean.
