Morphology

engram = gram (semi-transparent) = en + gram + en

Formed from classical combining elements en- ('in') + -gram ('written/record'), which yields a logical 'memory trace' meaning but uses technical classical morphemes unfamiliar to average learners.

Etymology

The word engram comes from Greek parts en- ('in') and gramma ('a written thing' or 'mark'). You can see the same gram in words like telegram, which helps you remember the idea of 'writing' or a record. So an engram is a 'mark' written 'in' the brain — a physical trace that holds a memory.
