What does synth mean?
A synth is an electronic musical instrument that creates sounds using electronic components rather than recorded acoustic instruments. In music discussions, the word can also refer to a synthesized sound, texture, or style. Synths became especially important in electronic and popular music, where they can imitate many conventional instruments or create sounds that have no direct acoustic equivalent. As a verb, “synthesize” means to bring separate elements together into a unified whole. Researchers synthesize evidence from multiple studies, chemists synthesize new compounds, and writers may synthesize ideas from different sources. The term therefore connects both technical production and intellectual combination. “Synth” is concise and familiar in musical settings, whereas “synthesize” is a more formal verb commonly encountered in scientific, academic, and critical contexts. Together, the noun and verb describe processes of creating something coherent from electronic or conceptual elements.
An electronic musical instrument that generates sound electronically; the term may also denote a synthesized sound or the characteristic sound of such an instrument.
"The song opens with a soft, atmospheric synth."
The shortened form is especially common in music production and popular-music discussion.
To combine separate elements into a coherent whole, especially by integrating ideas, evidence, components, or materials.
"The report synthesizes research from several disciplines."
This use is formal and common in academic, scientific, and analytical writing.
Plural synths refers to multiple electronic musical instruments or, more loosely, to distinct synthesized sounds.
"The producer layered several analog synths to create a dense wall of sound."
The word “synth” is a compact piece of musical shorthand: it helped name a new instrument and, eventually, an entire sonic identity.

Etymology of synth
The noun “synth” developed as a shortened form of “synthesizer,” a word built on the roots of “synthesis” and ultimately Greek synthesis, meaning a putting together or combining. The longer name was used for electronic devices that combined sound-producing elements, and “synth” became common in the second half of the twentieth century as electronic instruments entered popular music. The verb “synthesize” was borrowed directly from the related Greek and Latin formations and has long meant combining materials or ideas into a unified form.
