Tamil Kinship Terms Guide: Relationship Mapping

If your paatti calls someone "mama" and your amma calls the same person "chithappa", they might both be right — Tamil kinship terms shift depending on who's speaking, which generation, and which side of the family. Get the term wrong and you'll link the wrong parent in your tree.

Why kinship terms are tricky in genealogy

Tamil terms can encode:

• elder/younger ordering
• maternal/paternal side
• respect and social context
• household roles rather than strict biological links

Rule: treat kinship terms as clues; confirm via records and relationships.

---

High-value distinctions to capture

1) Maternal vs paternal side

If the term implies a specific side, store it explicitly:

• “maternal uncle” vs “paternal uncle”

2) Elder vs younger

Age ordering can resolve ambiguity and same-name collisions.

3) Relationship-by-marriage

Some terms refer to in-law roles; never assume biological linkage.

Disambiguation method (use this every time)

Step 1 — Identify the speaker

Who said “mama/athai/anna”? The term is defined relative to the speaker.

Step 2 — Identify the reference person

Is the term used relative to:

• the speaker’s parent?
• the spouse?
• a household elder?

Step 3 — Test against the timeline

Does the age ordering and generation make sense?

Step 4 — Confirm using one evidence anchor

Use at least one:

• spouse/parent name in a document
• household clustering
• wedding invitation relationship listing
• consistent address network

If you cannot confirm, store as “possible relationship” only.

How to store kinship terms safely (data model guidance)

For each relationship claim:

• term as spoken (raw)
• inferred relationship type (normalized)
• side: maternal/paternal/unknown
• confidence: confirmed/probable/possible
• evidence note

This prevents “hard commits” from conversational terms.

Common mistakes

• Treating conversational terms as strict biological relationships
• Ignoring the speaker perspective
• Merging people based on a term alone

Use the merge guide when uncertain: Avoid Duplicate Ancestors.
