茎
the main part of a plant that connects the roots to the twigs, leaves, and flowers
A stem is a vital part of a plant's anatomy that supports leaves, flowers, and fruits, and serves as a channel for transporting water, nutrients, and sugars throughout the plant. Stems come in various shapes and sizes, ranging from woody and rigid to soft and flexible, depending on the plant species. They can grow above or below ground, and they often exhibit nodes, where leaves, branches, or flowers emerge, and internodes, the spaces between nodes. Stems play a crucial role in the growth, structure, and overall health of plants, enabling them to thrive in diverse environments and adapt to changing conditions.

(in linguistics) the base form of a word after removing affixes
A stem is the base form of a word to which affixes, such as prefixes or suffixes, can be added to create new words or modify its meaning. The stem contains the core meaning of the word and can stand alone or serve as the foundation for further word formation. For example, in the word "unhappiness", the stem is "happy", which conveys the primary meaning, while "un-" and "-ness" are added to change the meaning and grammatical function. Stems are essential in linguistics for understanding word structure and the relationships between words in a language.
