Latin Subscript Small Letter L

Latin Subscript Small Letter L at U+2097 is a small baseline-lowered form of the Latin letter l, used when an l-shaped variable or label needs to appear as a subscript in plain text. It belongs to the Superscripts and Subscripts block, which contains compatibility characters for notation that would otherwise require text styling. Its main use is in technical and scientific notation copied into environments that do not support rich formatting, such as file names, data labels, chat, or plain-text documentation. For example, a physicist or engineer may use Vₗ for a voltage associated with an inductor-like label, a left-side label, or another locally defined quantity where the subscript l has been introduced in the surrounding text. It can also appear in linguistic, mathematical, and educational materials where variables are indexed by letters rather than numbers, such as xₗ to distinguish one member of a set from xᵣ or other related symbols. Because lowercase l can look very similar to the digit 1 or uppercase I in some fonts, this character is best used where the intended label is clear from context.
