Sum-Yu
Meaning
heart; words, speech, or language (心語)
The story
Sum-Yu in this collection is the Cantonese reading of 心語. 心 means heart, and 語 means words, speech, or language. The characters do the real work: a romanized syllable can match more than one Chinese character, so Sum-Yu does not carry one fixed meaning when the writing is unknown. Hong Kong given names are normally chosen in characters and then represented in Latin letters for English-language settings. A two-character given name may be spaced, hyphenated, or joined; the hyphen here simply keeps the pair visible. That pairing is the documented form in this collection. The US curve sits almost entirely at the floor, with only a small recent trace. That says more about what American records capture than about the name's life in Cantonese-speaking families. Read in its documented form, Sum-Yu is a concise wish built from sound, script, and family choice.
