Common Relationships

Uncle, Aunty, Nephew and Niece

  • The term “Uncle” is used by many English speakers for four relations – mother’s brother, father’s brother, husband of mother’s sister, and husband of father’s sister
  • Aunt is also used to define mother’s sister, father’s sister, wife of father’s brother, and wife of mother’s brother
  • Sister’s or brother’s son is known as a nephew. Sister’s or brother’s daughter is known as a niece.
  • Cousins is used to introduce children of uncle or aunt

Relations with Term “In-Law”

Any term in relationships ends with “in-law” shows that relationship is through marriage, not blood. In general the relationship terms “In-laws” are mentioned in hyphens (-). The plural is defined before “in-law”. For instance, it is “brothers-in-law”, not “brother-in-laws”.

Who’s who of them?

  • Mother-in-law is spouse’s mother and father-in-law is spouse’s father. If they get separated and remarry, their new partners are known as stepparents, not father-in-law and mother-in-law.
  • The wife of the son is referred as daughter-in-law and husband of a daughter is son-in-law. If your partner has children from last marriage, these are known as stepchildren, not daughters-in-law or sons-in-law. That person is their stepmother or stepfather, not mother-in-law or father-in-law.


Both sister-in-law and brother-in-law have several meanings

  • A sister-in-law could be
    • Wife of brother,
    • Sister of spouse, or
    • Spouse’s brother’s wife
  • A brother-in-law could be
    • A sister’s husband
    • Spouse’s brother
    • Spouse’s sister’s husband

Relationships defined with the terms “Great” and “Grand”

  • Relationships with the second generation are defined with “Grand” term
  • For a person, the first generation over them would be their parents like father and mother. The second generation is called the parents of the parents and they are known as Grandfather, Grandmother or Grandparents.
  • The third generation parents are known as Great Grand Father or Great Grand Mother.

The term Grand also applies to collateral relations. For example, brother of Grand Father is known as Grand Uncle and son of a nephew is known as Grand Nephew.  There are also fourth generation relationships, known as Great Great Grand. For example, Great Great Grand Son is the son of Great Grand Son.

How to Solve Blood Relation Problems Quickly?

In any aptitude test, blood relation is a very common topic. These questions may be given or asked directly as coded blood relations. Here are some of the blood relation shortcut tricks to decode these questions easily.

Apply Question to Yourself

It is the easiest way to solve the questions related to blood relations. You can relate yourself to every statement. Assume yourself or your name to the first name in the statement. Here’s an example to solve this type of question.


She is Rahul’s brother’s mom’s sister

In this statement, suppose Rahul is you

Similarly, your brother’s mother is your mother, of course.

Your mother’s sister is your Maternal Aunt

Hence, she is your Maternal Aunt.

If the question is short, this trick works. But don’t apply it for long questions as it will create conflicts.

Split the Question into Small Portions

The statement can get confusing when it is very long. So, you have to split every statement down into sub-statements and attend the problem.


He is the son of Prabha’s brother’s aunt’s husband

Here, assume yourself as Prabha

Your brother’s aunt is your aunt

Your aunt’s husband is your uncle

His son is your cousin. Hence, he is Prabha’s cousin

A*B refers to A is B’s son

What is the relation of F with P in F*B+C/P?

This way, you should start solving the question from right to left or left to right. This question has been solved from right to left. Mention each person’s gender clearly. This way, F is P’s nephew. Hence, P is the uncle or aunt of F and it is not possible to state anything.

Don’t Assume Gender

Don’t assume any person’s gender in the question which is just based on names. For instance –

Hitesh is Mithilesh’s brother and Mithilesh is Suresh’s brother. Who is Suresh for Hitesh?

Use the explanation above in this way –

Hitesh (m) => Mithilesh (m) => Suresh

In this example, whether Suresh is male or female not known. Hence, Suresh could be the sister or brother of Hitesh. Please keep in mind that person’s gender cannot be defined on person’s name. This information should definitely support person’s gender.

Here are some of the unsolved practice questions

  1. There are 8 family members – M, N, P, Q, R, S, T and U. This family has three couples. Along with their children, they live in three different cities – Ranchi, Chandigarh, and Delhi, but not in same order. Q is the mom of M & R. M is T’s uncle and S’s father. U’s spouse lives in Ranchi. U is N’s only sister-in-law. Who is P’s daughter-in-law? S neither lives with her aunt U nor in Chandigarh.

Who is Q’s husband among them?

  • U
  • P
  • N
  • Cannot be determined
  • None of them
  1. Husband of Sulekha is the only son of Nandini’s mom.
  2. Nandini’s husband and Sulekha’s brother are cousins.

What is the relationship between Sulekha and Nandini?

  • 1 is sufficient and 2 is not.
  • 2 is sufficient alone while 2 only is not sufficient.
  • Either 2 or 1 is sufficient
  • Both of them not sufficient
  • Both are sufficient

Points to Remember

  • Focus only on those points that provide maximum and definite details.
  • When it comes to concluding the relationship between two persons, you should be varied of the person’s gender who is discussed because there are chances of mistake when you assume the gender of the person that is not mentioned in the question or that cannot be collected from the information mentioned.
  • Read questions with care and identify the people between whom relation can be established. You may possibly relate yourself to the character given so it can be simple to understand.
