Blood Relations • Topic 1 of 4
Relation Terms
Lock in the vocabulary: paternal vs maternal (father's vs mother's side), in-laws, niece/nephew, first cousins, and the 'grand'/'great-grand' levels. Many SSC items are pure definition checks — 'mother's brother' is your maternal uncle.

Every blood-relation question becomes easy once you draw it. Use this fixed notation:
The vocabulary that gets tested
| Phrase | Means |
|---|---|
| Mother's / Father's brother | Maternal / Paternal uncle |
| Mother's / Father's sister | Maternal / Paternal aunt |
| Brother's / Sister's son | Nephew |
| Brother's / Sister's daughter | Niece |
| Son's wife / Daughter's husband | Daughter-in-law / Son-in-law |
| Wife's or husband's brother | Brother-in-law |
Paternal vs maternal. "Paternal" = father's side; "maternal" = mother's side. SSC often hides the answer in this one word, so translate each phrase to a single relation before combining.
