How does Korean word order compare with Japanese word order?

The Korean language and Japanese language share very similar sentence structures, despite their distinct vocabularies. Both are consistent subject–object–verb (SOV) languages, meaning the predicate typically appears at the end of the sentence.12

In both languages, the following word order principles apply:

• Modifier Placement: Modifiers always precede the elements they modify. Consequently, adjectives and relative clauses appear before the nouns they describe, and adverbs are placed before verbs.21
• Unmarked Order: The standard, unmarked word order for both languages is subject + indirect object + direct object + predicate.1
• Predicate Importance: In both systems, the predicate is the only essential component of a sentence; other elements are frequently omitted when they can be recovered from the context.21
• Grammatical Marking: Both languages utilize particles attached to nouns to indicate their grammatical roles, such as subject or object markers.21

While the two languages exhibit these significant structural parallels, scholars continue to debate whether these similarities arise from a common genetic origin or from long-term language contact.3
