叻

1 candidate reading from Wiktionary — genuine Chaozhou colloquial form not yet confirmed by a speaker. The second candidate reading (lag8) was dropped for this sense: the dossier attests lag8 only for a different, unrelated sense of this character (short for 石叻, an old name for Singapore, and an unrelated Internet-slang use), not for the 'smart/clever' sense drafted here.
