Morphology

LCA = L + C + A

This is an initialism/acronym: the letters do not transparently convey the meaning 'last common ancestor' without knowing the expanded phrase.

Etymology

LCA is short for last common ancestor, meaning the most recent shared ancestor of two groups, like the point where two branches meet on a family tree, and that is why scientists use LCA to name that shared ancestor.
