A small column-like structure, especially in biology referring to small columnar anatomical features.
From Latin 'columella', the diminutive of 'columna' (column). Used in anatomical and botanical Latin to describe miniature column-shaped parts.
The diminutive form '-ella' is so common in scientific naming that when biologists discover tiny structures, they automatically get this 'small' suffix added—it's a built-in way to show size through language.
