senmon[sẽ̞mːõ̞ɴ]
専門 (senmon) is the Japanese word for a field of study or a particular area of expertise.
Use 専門 to refer to a specialty or a specific area of knowledge. You can use the compound 専門分野 (senmon bun'ya) to specifically refer to a 'field of study' or 'specialized area'.
What does it mean word for word?
The word is composed of the kanji 専 (special/exclusive) and 門 (gate/door/sect), literally meaning a 'special gate' or a specialized field.

Did you know?
- The character 門 (mon), meaning 'gate', is used in Japanese to denote a school of thought or a family lineage, much like the English word 'sect' or 'house'.
- In Japanese professional introductions, someone might say 専門外です (senmon-gai desu) to politely signal that a question is outside their expertise and they cannot provide a reliable answer.
- While 専門 refers to a field of study, the word 専攻 (senkō) is used specifically for a student's 'major' in a university setting.
