Pronunciation: [spˈa͡ɪklət] (IPA) 
The word "spikelet" is spelled with the IPA phonetic transcription /ˈspaɪklət/. The first syllable is pronounced with a long "i" sound, and the second syllable has a short "u" sound followed by a silent "e". The spelling of this word can be confusing, as the "k" is pronounced as a "hard" "c". A spikelet is a small cluster of flowers that make up a larger inflorescence in certain types of plants, such as grasses.
A spikelet, in botanical terms, refers to a small unit or component of a inflorescence structure specific to certain plants, particularly in the grass family (Poaceae). It is composed of one or several florets enclosed within thin bracts called glumes. The spikelet forms the basic building block of the inflorescence, also known as the flowering structure, in these grasses.
Typically, a spikelet consists of a central axis or rachilla, with one or more florets attached along its length. Each floret contains the reproductive organs, including the stigma, styles, stamens, and ovary. The structure is often surrounded by a pair of glumes, which are modified leaves that serve to protect the florets within.
The arrangement and composition of spikelets can vary among grass species. Some grasses may have spikelets that contain a single floret, while others may have multiple florets. These spikelets can be densely clustered together in various arrangements, such as spikes or racemes, which contribute to the overall inflorescence of the plant.
The spikelet serves a vital function in the reproductive biology of grasses as it facilitates the development and dispersal of their seeds. Pollination of the floret within the spikelet occurs through wind, insects, or self-pollination mechanisms. As the florets mature, the grains or seeds inside are released, enabling propagation and future growth of the plant. Overall, the spikelet is an essential structure for the successful reproduction and survival of grass species within the Poaceae family.
A small spike; in bot., a small cluster of flowers, as in grasses.

The word "spikelet" has its origins in the combination of two words: "spike" and "-let".
The term "spike" refers to a long, slender, and pointed structure. It can be traced back to the Old Norse word "spīk" which means "spike" or "nail". This word was later adapted by Middle English as "spike" with the same meaning.
The suffix "-let" is a diminutive suffix derived from Middle English and Old French. It is used to denote smallness or a smaller version of something. In this case, it is added to "spike" to create "spikelet", indicating a small spike or a diminutive spike.
Overall, the etymology of "spikelet" reflects its meaning as a small or miniature spike.
