What is the difference between different ways of expressing similarity? I see things like,
- La niña parece a su hermana.
- Compró dos vestidos semejantes.
- Quiere una fiesta de cumpleaños similar a la de su hermano mayor.
- Son parecidos como dos gotas de agua.
English doesn't have obvious analogs to parecer or semejante in this context. Where would you use one or another of these words?
