Meaning
The kanji 麦 (mugi) refers to various cereal grains, most commonly wheat and barley. It can also encompass oats and rye. This character is fundamental in Japanese for agricultural products and foods made from these grains.
Its etymological roots trace back to the ancient Chinese character 麥. The upper component, 來, was originally a pictograph depicting a stalk of barley with heavy, drooping ears of grain. The lower part, 夂, signified a foot or the concept of 'coming.' Historically, barley was a crop introduced to ancient China from foreign lands. This origin likely inspired the idea of grain 'coming' from elsewhere. Over time, the character's meaning evolved and simplified to its current form, 麦.
Interestingly, the character 来 (meaning 'to come') shares its ancient form with the upper part of 麦. This shows a historical linguistic connection where the two characters once had the same visual representation before their meanings diverged. The simplified form, 麦, clearly depicts a plant with its head and stem, making its association with grains visually intuitive.
This kanji has 7 strokes and is taught in the second grade of Japanese elementary schools, highlighting its basic and essential role in everyday vocabulary. It also serves as its own radical (radical 199), further emphasizing its distinct visual and semantic identity.
Readings
On'yomi (音読み) — Chinese-derived readings
The primary On'yomi (Chinese-derived reading) for 麦 is バク (baku). You'll typically find this reading in more formal, scientific, or technical compound words. These often relate to specific properties or processed forms of grains, or carry a more academic nuance.
麦芽 (bakuga) — malt. This compound refers to germinated cereal grain, primarily barley, used in brewing and other food industries. It highlights how barley is processed, for example, for beer production.
麦酒 (bakushu) — beer (a more formal or archaic term). While ビール is the common modern word for beer, 麦酒 directly translates to 'grain alcohol' or 'barley alcohol,' indicating its origin from grains like barley.
Kun'yomi (訓読み) — Native Japanese readings
The main Kun'yomi (native Japanese reading) for 麦 is むぎ (mugi). This is the most common reading, used when the kanji stands alone to refer to wheat or barley in general. It also appears in compounds that describe the grain itself in a more colloquial or direct way.
麦 (mugi) — wheat, barley, oats, rye. This is the direct, standalone reading for these general grain terms.
麦茶 (mugicha) — barley tea. A popular summer beverage in Japan, this compound uses the native Japanese reading to describe a common product made from barley.
小麦 (komugi) — wheat. While 'ko' (小) is an On'yomi reading, 'mugi' (麦) here retains its Kun'yomi, making this a common mixed reading compound specifically for wheat. This term is frequently used, for instance, when talking about wheat flour (小麦粉).

Memory Tip
To remember the kanji 麦, visualize its components: the top part (which resembles 来, 'to come') can be seen as the full, drooping head of a grain stalk. The bottom part suggests roots or a stable base. Imagine golden grains of wheat or barley emerging from the earth, ready for harvest. The overall shape evokes a bountiful plant, bringing forth food. Think of a field of grain, with the stalks 'coming' out of the ground.
