l2

A second language (a language being learned, as opposed to a mother tongue).

That is, for almost all late second language (L2) learners, the phonetic realization of phonological structures in the L2 is markedly different from native-language patterns.

This advantage was pertinent in the Hong Kong context where English is largely an L2 language, although would not be expected to be as large in an L1 context.

Abbreviation of Lagrange point 2, located beyond the smaller object on a line passing through the centers of the smaller and larger objects.

Unlike the Hubble telescope, which orbits a few hundred miles above the Earth’s surface and is relatively accessible for servicing missions, the JWST will be located at what is called the L2 point, a location about a million miles farther away from the sun than the Earth.

Short for second level in various contexts

In typical Intel chips L2 bandwidth is half of L1 bandwidth.
