What is "jyutping"

Jyutping (; ) is a romanisation system for Cantonese developed by the Linguistic Society of Hong Kong (LSHK), an academic group, in 1993. Its formal name is The Linguistic Society of Hong Kong Cantonese Romanisation Scheme. The LSHK promotes the use of this romanisation system.

The name Jyutping (itself the Jyutping romanisation of its Chinese name, 粵拼) is a contraction consisting of the first Chinese characters of the terms jyut6 jyu5 (粵語, meaning " Cantonese speech") and ping3 jam1 (拼音 "phonetic alphabet").
