Looi
Open-knowledge reference entry
Looi is a surname.
Origins
Like many other similarly-spelled surnames (Lui, Loi, Louie, etc.), it can originate from either of two Chinese surnames which are almost homophonous in Cantonese, though pronounced distinctly in Mandarin:
Léi (雷), meaning "thunder" (Jyutping: Leoi4; Cantonese Yale: Lèuih). The spelling Looi might also originate from its pronunciation in various Southern Min dialects, e.g. Hokkien (Pe̍h-ōe-jī: Lûi) or Chaoshan (Peng'im: Lui5).
Lǚ (呂), a toponymic surname from the ancient state of Lü (Jyutping: Leoi5; Cantonese Yale: Léuih; note the differing tone). The pronunciation in other varieties of Chinese is not similar to the surname meaning "thunder".
As a Dutch surname, Looi originated both as shortened version of van de Looi with the tussenvoegsels dropped, and as a patronymic surname derived from the given name Looi. That given name is a regional hypocorism of various other given names: it may be short for Ludolf, or for Lodewijk in Groningen and the southern Netherlands, or for Eligius in Friesland. Alternative spellings include Looij.

This brief starts where responsible research should: with the source description of “Looi” as open-knowledge reference entry. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as open-knowledge reference entry. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 26, 2024. The linked authority identifier is Q85782110. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2007 and 1947.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
