Wha'ts the difference between concuñado and coñado?
There is a question that
El esposo de mi hermana es el__________de mi esposo.
Why the correct answer is concuñado rather than cuñado?

Concuñado is used when it is between person A and person B, which is not involved with yourself?
And cuñado is used between the relationship between yourself and the other person.

For example, El esposa de mi padre es la concuñada de el esposa del hermano de mi madre.
El hermano de mi esposo es mi cuñado.

Hmmm, these really throw me out. Can anyone help me?

Answer

These words are different because there is not a "blood" relationship between the 2 esposos.

For you, your sister's husband is your cuñado.
For your sister, your husband is her cuñado.

For your husband, your sister's husband is his concuñado.
For your sister's husband, your husband is also his concuñado.

Answer

Cuñado : Your sister's husband
Concuñado : The "Cuñado" of your Sister is your... Concuñado

Lol. got it?

Answer

La esposa* when you mention a female person is used the "la" but when you mention a man the "el" is used.

Answer

My two cents - in several parts of Latin America, "concuñado(a)" gets shortened to "concuño(a)". Remember that context for proper usage :-)
