FAQ
What is the difference between あいだ (間) and ま (間)?
Generally, 'あいだ' refers to a clear interval between two points in space or time (e.g., between A and B). On the other hand, 'ま' is often used in slightly more abstract or idiomatic expressions, referring to a gap where something happens or spare time (e.g., 間に合う - to be in time).
Why is 人間 read as にんげん instead of にんかん?
In some Japanese kanji words, sequential voicing (rendaku) or phonetic changes occur to make pronunciation smoother. '人間' is an exceptional reading that settled as 'にんげん' instead of 'にんかん' for ease of pronunciation, so it is best to memorize it as a whole.
