The barred lambda (Ƛ ƛ) (U+A7DC Ƛ LATIN CAPITAL LETTER LAMBDA WITH STROKE, U+019B ƛ LATIN SMALL LETTER LAMBDA WITH STROKE), is a modified letter of the Greek alphabet, commonly encountered in North American linguistics.

[1] It is also used in Americanist phonetic notation, where it is also known as running man,[2] to transcribe [t͡ɬ].

It was first used in a phonetics context in American Anthropologist in 1934: λ for [dl] has been used in Eskimo by Jenness ... ƛ for [tł] is an innovation formed from λ as ł from l.[3]It is also used for the affricate [t͡ɬ] in transcribing the Sahaptin language, e.g., iƛúpna ‘he jumped’, and it is commonly used for the same purpose in several languages of the Caucasus.

In addition, its counterpart with a combining comma above right (U+0315), ƛ̓ [fr], is used for many of the Salish languages, such as Klallam, for an ejective lateral affricate.
