Remember we say old, older and oldest when comparing 3 things.
For example:
*Jane is older than me but Mary is the oldest.- This means that Mary is the first born, Jane is the second born and you are the last born.
I am the youngest in a family of three girls.
*Mary is the oldest sister and I am the youngest.- This means that Mary is the first born in your family and you are the last born. However in this sentence it doesn't imply how many you are in the family.
3つのことを比べる時は"old"、"older "、そして"oldest"と言うことを覚えておいてください。
例:
*Jane is older than me but Mary is the oldest. (ジェーンは私よりも年上ですがメアリーが一番年上です。)
- これはメアリーが長女、ジェーンが次女、そしてあなたが末っ子であるという意味です。
*I am the youngest in a family of three girls. (私は三人姉妹の一番年下です)
*Mary is the oldest sister and I am the youngest. (メアリーが長女で私が一番年下です)
- これはメアリーがあなたの家族の長女でありあなたが末っ子であるという意味です。しかしこの文ではあなたが何人家族であるかは示していません。
"My eldest sister is tall."
"Sarah is the second eldest sister"
"I have two siblings other than me."
Jane is the oldest of the sisters and that makes her the firstborn child of the family. Nikita was the second born child of my parents and she is my second eldest sister. I am the youngest of the three children. "Siblings" is another word for sister or brother. My eldest sister and "second eldest" sister are four years of age apart.
"My eldest sister is tall."（私の一番上の姉は背が高いです）
"Sarah is the second eldest sister"（サラは二番目の姉です。）
"I have two siblings other than me."（私にはきょうだいが二人います）
----
Jane is the oldest of the sisters and that makes her the firstborn child of the family.
（ジェーンは一番上の姉で、家族にとっての最初の子どもです）
Nikita was the second born child of my parents and she is my second eldest sister.
（ニキータは両親にとって二人目の子どもで、私にとっては二番目の姉です）
I am the youngest of the three children.
（私は三人の子どもの中で一番下です）
"Siblings" は「きょうだい」のことで、性別に関係なく使われます。
My eldest sister and "second eldest" sister are four years of age apart.
（私の一番上の姉と二番目の姉は年が4歳離れています）
I have two older sisters: Jane is the elder and Samantha is the younger
We can use elder and eldest as an alternative to older and oldest to explain the order of birth of family members. We use elder when we speak about two brothers or sisters (also called siblings), or two sons or daughters: his elder brother, his elder sister. their eldest son, their eldest daughter, their eldest child.
"Of my two younger brothers, John is the elder."
家族の誕生の順序を説明するために「old」や「oldest」の代わりに「elder」や「eldest」を使うことができます。
2人の兄や姉（siblingsとも呼びます）もしくは、2人の息子や娘について話すときに「elder」を使います。
上の兄や上の姉、上の息子、上の娘、上の子供のように。
Of my two younger brothers, John is the elder.
2人の弟のうち、ジョンが年上です。
Eldest sister means oldest sister.
You could say. I am the youngest of 3 sisters. Carrie is the eldest, Lisa is the middle sister and I am the youngest.
「eldest sister」は「長女（oldest sister）」という意味です。
例えば：
I am the youngest of 3 sisters. Carrie is the eldest, Lisa is the middle sister and I am the youngest.
（私は三姉妹の末っ子です。Carrieが長女、Lisaが次女、一番下が私です）
Your middle sister would be your "older sister", because "older" is older than you, but not the most old.
Oldest is more than older, so you would say oldest sister.
