喇 is a phonetic character used primarily in loanwords and onomatopoeia. In this reading (lā, first tone), it appears in words like 喇嘛 (lāma, 'lama') and 哈喇 (hāla, 'rancid'). As a standalone character it carries no independent meaning—its function is purely phonetic. Learners should note that 喇 also has a common third-tone reading (lǎ) in words like 喇叭 (lǎba, 'trumpet/horn'), so context determines the tone.
