Morphology

milliamp = amp (transparent) = milli + amp

Standard SI prefix 'milli' (one thousandth) added to 'amp' (short for ampere) yields the expected meaning of one thousandth of an ampere.

Etymology

The word milliamp is made of two parts: the prefix milli-, meaning 'one thousandth' as in milligram, and amp short for ampere, the unit of electric current. So a milliamp is 'one thousandth' of an amp, which explains why it names a very small electric current.
