Hello. If you want to add a new paragraph, then do this:
#import "@preview/leipzig-glossing:0.5.0": example
#example((
header: [Hunzib (van den Berg 1995:46)],
source: ([ождиг], [хо#super[н]хе], [мукъер]),
transliteration: ([oʒdig], [χõχe], [muqʼer]),
morphemes: ([ož-di-g], [xõxe], [m-uq'e-r]),
additional-lines: (
(
[boy-#smallcaps[obl]-#smallcaps[ad]],
[tree(#smallcaps[g4])],
[#smallcaps[g4]-bend-#smallcaps[pret]],
),
([at boy], [tree], [bent]),
),
translation: [
"Because of the boy, the tree bent."
"Из-за мальчика дерево согнулось"
],
))
If the same paragraph with a line break:
#import "@preview/leipzig-glossing:0.5.0": example
#example((
header: [Hunzib (van den Berg 1995:46)],
source: ([ождиг], [хо#super[н]хе], [мукъер]),
transliteration: ([oʒdig], [χõχe], [muqʼer]),
morphemes: ([ož-di-g], [xõxe], [m-uq'e-r]),
additional-lines: (
(
[boy-#smallcaps[obl]-#smallcaps[ad]],
[tree(#smallcaps[g4])],
[#smallcaps[g4]-bend-#smallcaps[pret]],
),
([at boy], [tree], [bent]),
),
translation: [
"Because of the boy, the tree bent." \
"Из-за мальчика дерево согнулось"
],
))
P.S. Don’t forget to put language identifier for code blocks.
