Idioms and Expressions about Family

Hello, dear English learners! In this lesson, we will look at useful idioms about family in English. These expressions can help you talk about family relationships, shared traits, loyalty, and life at home in a more natural and expressive way. They are especially useful for B2–C1 learners and for students preparing for Cambridge B2 First and C1 Advanced.

Family is one of the most common topics in everyday conversation, so it is no surprise that English has many idioms and fixed expressions connected to family life, family resemblance, relationships, and shared history.

Some of these expressions are warm and affectionate, while others are humorous, critical, or even a little old-fashioned. Still, they are all useful if you want to sound more natural and understand English better in context.

In today’s lesson, we’ll look at idioms and expressions about family, with clear meanings and example sentences to help you remember them more easily.

Let’s keep it in the family and begin.

1. The apple doesn’t fall far from the tree

We use this idiom to say that a child is very similar to their parent, especially in character, behaviour, or ability.

Examples:

• His father was an excellent musician, and now Tom plays three instruments. The apple doesn’t fall far from the tree.
• Miranda is ambitious and determined, just like her mother was at her age. The apple doesn’t fall far from the tree.

2. A chip off the old block

This expression also means that someone is very much like their mother or father.

Examples:

• Charlie is just like his father — confident, funny, and talkative. He’s a chip off the old block.
• Emma’s a chip off the old block. She has her mother’s kindness and patience.

3. Like father, like son / Like mother, like daughter

We use these sayings when a child behaves in a similar way to their parent.

Examples:

• James became a lawyer, just like his father. Like father, like son.
• Sophie loves gardening as much as her mother does. Like mother, like daughter.

4. Black sheep of the family

The black sheep of the family is the person who is considered different from the others, often in a negative or disapproved-of way.

Examples:

• David was seen as the black sheep of the family because he was always getting into trouble.
• Every family seems to have a black sheep — someone who never quite follows the expected path.

5. Blood is thicker than water

This idiom means that family relationships are usually considered stronger or more important than other relationships.

Examples:

• They may argue all the time, but when there is a real problem, they support one another. Blood is thicker than water.
• Ryan was raised to believe that blood is thicker than water, so he always stands by his relatives.

6. Flesh and blood

Your flesh and blood are your close relatives — especially members of your own family.

Examples:

• She couldn’t turn her back on her son. He is her own flesh and blood.

7. Kith and kin

This slightly old-fashioned expression means friends and relatives.

Examples:

• The whole village seemed to come to the wedding, along with all our kith and kin.
• After retiring, he returned to his hometown to be near his kith and kin.

8. Run in the family

If a characteristic, talent, or illness runs in the family, several family members have it.

Examples:

• Heart disease runs in the family, so she tries to live a healthy lifestyle.
• Musical talent clearly runs in their family — they can all sing beautifully.

9. Born with a silver spoon in your mouth

If someone is born with a silver spoon in their mouth, they are born into a rich or privileged family.

Examples:

• He was born with a silver spoon in his mouth and never had to worry about money.
• Not everyone is born with a silver spoon in their mouth, so success usually takes hard work.

10. Breadwinner

The breadwinner is the person in a family who earns the money that supports the household.

Examples:

• Her father was the main breadwinner for many years.
• After her husband lost his job, Maria became the family’s breadwinner.

11. Bob’s your uncle

This very British expression means there you are, it’s done, or that’s the solution.

It is not really about family life, but it contains family vocabulary and is a fun idiom to know.

Examples:

• Just fill in the form, press submit, and Bob’s your uncle.
• Add a little cream, stir it well, and Bob’s your uncle — dessert is ready.

12. Follow in someone’s footsteps

If you follow in someone’s footsteps, you do the same job or choose the same path in life as an older family member.

Examples:

• Olivia followed in her mother’s footsteps and became a teacher.
• No one expected Ben to follow in his father’s footsteps and join the army.

13. Keep it in the family

This expression means to keep something within the family rather than involving outsiders.

Examples:

• They decided to keep the business in the family.

14. Family ties

Family ties are the relationships and emotional bonds between family members.

15. A family man / A family woman

A family man or family woman is someone who cares deeply about their family and enjoys spending time with them.

Examples:

Examples:

Examples:
