Lagi means: A Singlish particle borrowed from Malay meaning 'more,' 'even more,' or 'still more,' used to intensify comparisons. In casual Singaporean speech, 'lagi' can appear before adjectives or verbs to add. It is mainly Singaporean English and may not be understood outside that context. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour.
