• Challenges arise with isolates and languages with limited historical documentation

Typological classification

• Categorizes languages based on structural features
• Focuses on phonological, morphological, and syntactic characteristics
• Includes classifications (agglutinative, fusional, isolating)
• Allows for cross-linguistic comparisons regardless of genetic relationships
• Reveals patterns of language structure across unrelated languages

Areal classification

• Groups languages based on geographic proximity and shared features
• Identifies linguistic areas or Sprachbunds where unrelated languages converge
• Reflects language contact and mutual influence over time
• Examples include the Balkan Sprachbund and the Mainland Southeast Asia linguistic area
• Challenges traditional family tree models of language relationships

Language family trees

• Language family trees visually represent the relationships between languages within a family
• These trees help linguists and humanities scholars understand language evolution and historical connections
• Studying language family trees provides insights into cultural diffusion and societal changes over time

Branching patterns

• Represent divergence of languages from a common ancestor
• Show chronological order of language splits
• Include binary and multifurcating branches
• Reflect historical events (migrations, conquests) influencing language development
• May be revised as new evidence emerges or analytical methods improve

Subgroups and subfamilies

• Represent intermediate levels of classification within a family

Sound changes across families

• Regular sound changes occur within and across language families
• Grimm's Law describes consonant shifts in Germanic languages
• Sound changes can be conditioned by linguistic environment
• Comparative method relies on identifying regular sound correspondences
• Understanding sound changes helps in reconstructing proto-languages

Lexical borrowing between families

• Words can be borrowed across language family boundaries
• Loanwords provide evidence of cultural contact and exchange
• Borrowing can occur due to trade, conquest, or cultural prestige
• Examples include Arabic loanwords in Persian (Indo-European)
• Identifying borrowed words is crucial for accurate genetic classification

Grammatical evolution within families

• Grammatical features change over time within language families
• Includes shifts in word order, case systems, and verbal morphology
