What does second cousin mean in spanish?
In Spanish, a second cousin is called a primo segundo.
Your cousin once removed is the child of your cousin who is not described as removed, or the parent of your cousin who is not removed. For example, your second cousin once removed is the child of your second cousin, or the parent of your third cousin, depending on which of you is in the older generation.
Asking about your second cousin's cousin's cousin is asking about a complex but poorly defined relationship. Are the cousins of the second cousin his first cousin, second cousin, fifth cousin twice removed, or something else. It is likely that a cousin's cousin's cousin is not related to you at all. It is also possible that your second cousin's first cousin's first cousin is also your second cousin.
