αδελφος

The noun αδελφος (adelphos) means brother (Matthew 1:2, Luke 3:1), or more generally, someone with whom one shares a common origin (Acts 3:22, Romans 9:3), or a common perspective, objective or modus operandi (Matthew 12:50, Mark 10:29-30, Romans 8:29; see our article on the word υιος, huios, meaning son for a discussion of the use of this word for these more general relationships). Our noun αδελφος (adelphos) is used 345 times in the New Testament; see full concordance.

The feminine version of our word is αδελφη (adelphe). This word means sister with the same range of application as the masculine counterpart: from a female sibling (Luke 10:39) to a female fellow believer (Romans 16:1). This word occurs 25 times; see full concordance.

Our words are formed from the prefix α (a), which in this case is a collative which denotes unity, and the noun δελφυς (delphus), meaning womb (this word is not used in the Bible).
