Family Tree (Pointing)
'Pointing-to-a-photo' items: a person describes a relation through themselves ('She is the daughter of my grandfather's only son'). Resolve the innermost phrase first, then build outward.
Resolve the innermost phrase first
Pointing puzzles nest relations: "He is the son of my grandfather's only son." Unwrap from the inside:
- "my grandfather's only son" = the speaker's father (the grandfather's only son must be your father).
- "the son of my father" = the speaker himself (or the speaker's brother).
Technique. Replace each bracketed phrase with a single word in your head: "grandfather's only son" → "father", then "son of father" → "me/brother". Peel one layer at a time.
Common inner phrases
| Phrase | Resolves to |
|---|---|
| my father's wife | my mother |
| my mother's only son | me / my brother |
| my father's only son | me / my brother |
| my grandfather's only son | my father |
| the only brother of my mother | my maternal uncle |
