preamplifier

/pɹˈiæmplˌɪfaɪɚ/ noun

A voltage amplifier for amplifying a low-level input signal; its output is the input to a higher-level amplifier.

Word Origin Preamplifier is pre- 'before' + amplifier. Amplifier comes from amplify, from Latin amplus 'large' + -ify 'to make' — so to make larger. The root amplus also gives us ample and amplitude. The -ify suffix is from Latin -ficare, from facere 'to make', which also gives us magnify, classify, purify, and verify. So a preamplifier is something that makes the signal larger before the main amplifier does its job.
