Sori is a term commonly used in botany to describe the small, round clusters of tiny spores found on the underside of fern fronds. The word is spelled as /sɔːri/ in IPA phonetic transcription. The first sound, /s/, is an unvoiced alveolar sibilant, while the vowel sound is represented by /ɔː/, a long open-mid back vowel. The final sound, /r/, is an alveolar approximant. The spelling of sori is consistent with the traditional English language spelling rules, with the vowel sound represented by the letter "o."
Sori is a noun that is primarily used in the field of biology and botany. It refers to a small cluster or group of spore-producing structures found on the underside of a fern frond or fern leaflet. These structures are commonly located along the veins or midrib of the leaf and are typically positioned in an organized pattern. Sori are a vital part of fern reproduction.
Each individual sorus, which is the singular form of sori, contains numerous sporangia. These sporangia are specialized structures responsible for producing and releasing spores, which are essential for fern dispersal and propagation.
Sori are typically characterized by their round or elongated shape and can vary in size depending on the fern species. They are often covered by a protective structure called an indusium, which shields the developing sporangia from external environmental factors until they are ready to release spores.
The presence of sori on fern leaves is a distinctive characteristic that aids in the identification and classification of fern species. They play a crucial role in the fern life cycle by facilitating the release and dispersal of spores, which then germinate into new fern plants. Overall, sori are important reproductive structures in ferns, contributing to their survival and proliferation in various ecosystems.
• In bot., the patches of fructification on the back of the fronds of ferns-see sorus.
• In bot., a cluster of sporangia in ferns.

The word "sori" has multiple origins and meanings, depending on the context.
1. In botany: "Sori" refers to clusters of spore-bearing structures found on the underside of fern fronds. The word "sori" originates from the Greek word "sōron", meaning heap or pile.
2. In Korean language: "Sori" means sound or voice. It comes from the Korean word "소리" pronounced as "sori".
3. In Japanese language: "Sori" refers to the gentle curve or convex shape found in traditional Japanese swords or blades. The word originates from the Japanese term "sori" (剃) meaning to curve or bend, which might be derived from the verb "soru" (反る) indicating to bend backward.
