Morphology

long + since

The meaning 'a long time ago' is directly derivable from combining 'long' (an extended duration) with 'since' (from a point in the past), yielding a compositional temporal sense. This is a common, predictable pattern in English (and has parallels in other languages), so a B1 learner who knows both constituents will generally infer the MWE's meaning.

Etymology

Long since comes from putting long, meaning a long time, before since, meaning 'from that time until now'. You can imagine a long gap between then and now, so it means 'a long time ago'.
