About this kanji
The kanji 凸 primarily means "convex" or "uneven." It is mostly used as a noun, representing a surface that bulges out. A common compound is お凸 (おでこ), which means "brow" or "forehead." Another interesting compound is 凸凹 (でこぼこ), which describes an uneven surface or roughness. You can also see the word 凹凸 (おうとつ), which refers to the concept of unevenness as well. This kanji is helpful when discussing shapes or describing something that isn't flat. If you think about a beetle, it often has a convex shape on its back, which is another way the kanji connects to everyday images.
Example sentences
そのテーブルは中央が凸になっている。
The table has a convex center.
