The words I chose that have the same denotation is “sister’ and “sibling”. I chose these words because they could mean the same thing or something different, I could say “I have two sisters” and “I have two siblings” and the sentences could be saying the same thing, or “siblings” could mean brothers or a brother and a sister. When someone says they have a sister, we automatically know what gender they are talking about when they are referring to a sibling. When someone says they have a sibling or siblings, we don’t know whether they are referring to a brother or a sister.
