EK-oh/ˈekəʊ/

An echo is a sound reflected back; as a verb, to send that sound, or to repeat an idea: an echo of; echo the findings. Reverberation is a close physics twin; repeat is everyday. Measure the echo time in the physics practical; an echo of the Act still needs the clause. Mix-up: echo vs eco; ache; do not write echo for a slogan “your voice” with no reflection or named source.
