Meaning
The kanji 異 (い / koto) primarily conveys 'different,' 'unusual,' or 'strange.' While similar to 'other,' it carries a stronger connotation of being distinct or out of the ordinary. When you encounter 異, envision something that stands apart, doesn't quite fit, or isn't what you'd expect. It can evoke wonder or curiosity, suggesting something 'extraordinary' or 'unique.' However, it more often leans towards 'abnormal' or 'unconventional'—think of an unusual phenomenon or a strange custom.
The origin of 異 is quite intriguing. One theory posits that the character is an ideograph depicting a person wearing a mask or an unusual costume during a ceremony, thus implying 'different' or 'strange.' Another theory suggests it combines 田 (field) with 廾 (two hands) and 𠄞 (a roof or cover, signifying a boundary or separation). This combination might suggest a field that stands out from others, or items that are separated and thus distinct. While its precise etymology is debated, the visual elements consistently hint at something out of the ordinary or set apart.
With 11 strokes, 異 is taught in the 6th grade of Japanese elementary schools, making it a common and fundamental character. As an N2 level kanji, intermediate Japanese learners will find it essential to understand and apply it in many situations.

異口同音 (ikudōon) — While イ is the On'yomi here, the idea of 'different' mouths making the 'same' sound connects conceptually. This idiomatic expression means 'unanimously' or 'with one voice,' literally translating to 'different mouths, same sound.' It describes when many people say the same thing without prior arrangement.

Memory Tip
Imagine the kanji 異 as a story: The top part, 田 (ta), represents a 'rice field.' Below it, two 'hands' (part of the ancient form, now simplified) are holding something. But what could they be holding? They're grasping something so 'different' or 'unusual' that it clearly stands out in the otherwise ordinary rice field! Perhaps it’s a strange, foreign plant, or a peculiar object. This 'different' item in the field makes it truly unique and uncommon. Thus, 異 signifies something 'different' in a field, possibly held by hands, making it 'strange' or 'unusual.'
