For example...
- the prefix "-e" ("email," "ecommerce")
- the suffix "-gate" ("Monicagate," "Russiagate")
The first touchscreen user interface was developed in 1972 for the control room of the particle accelerator at CERN (The European Organization for Nuclear Research).
@MaryJeanAdams Different languages have different numbers of phonemes. A phoneme is the smallest meaningful unit of sound in a language. For example, the word "things" is composed of four phonemes: th, i, ng, and z.
