People often search for “niece or nephew” because they want to know which word describes a particular family member.
The confusion can also come from similar words such as cousin, aunt, uncle, great-niece, and great-nephew. Some learners also wonder if the words change between British and American English.

My sister’s daughter is my niece.
You can use niece if the person is a child, teenager, or adult.

Niece and Nephew in Marriage Relationships

Cambridge includes these relationships in its definitions of both words.
The Origin of Niece or Nephew
The words niece and nephew have long histories. English borrowed both words from Old French, and their older meanings were broader than their meanings today.
Origin of Niece
Niece entered English around the early 14th century. It came from Old French niece, which meant “niece” or “granddaughter.” The word ultimately connects to Latin neptia, a feminine form related to nepos.
The meaning changed over time.
In earlier English, niece could refer to a granddaughter or another female descendant. By around the 17th century, English speakers had narrowed the word toward its modern family meaning.
Origin of Nephew
Nephew also entered English around the early 14th century. It came through Old French neveu from Latin nepos, which could mean “grandson,” “nephew,” or “descendant.”
The spelling nephew developed later. English changed the spelling to include -ph- after the 14th century, although the original pronunciation did not contain the sound that the spelling might suggest.
Why Do the Words Look So Different?
Today, my niece and nephew look quite different.
Their history explains why. English borrowed them through different French forms and developed their spellings over many centuries.
So, you should not expect a simple spelling pattern such as:
niece = female version of nephew
Instead, treat them as two separate vocabulary words.
British English vs American English Spelling
British and American English use niece and nephew with the same meanings and spellings.
You do not need to change either word when writing for a British or American audience. Cambridge lists both words in its British and American dictionary resources.

| Female sibling’s child | niece | niece |
| Male sibling’s child | nephew | nephew |
| Plural | nieces and nephews | nieces and nephews |
| Female spelling | niece | niece |
| Male spelling | nephew | nephew |
| Meaning | Same | Same |
| Example | My niece lives nearby. | My niece lives nearby. |
Pronunciation
The spelling stays the same, but pronunciation can vary slightly by accent.
Cambridge lists niece with the pronunciation /niːs/. It lists nephew with UK and US pronunciation variants, including /ˈnef.juː/ and /ˈnev.juː/.
These pronunciation differences do not change the meaning.
