Mat 12:31 Therefore I tell you, All manner of sin and blasphemy shall be forgiven men: but the blasphemy [against] the [Holy] Ghost shall not be forgiven men.

"All manner of" is from the Greek pas, which means "all," "every," "the whole," and "everything."

"Sin" is from the Greek hamartia, which means "to miss the mark," "failure," "fault," and "error." Only in religious uses do it become "guilt" and "sin."

"Blasphemy" is from blasphêmia, which means "slander," "profane speech," "word of evil omen," and "irreverent speech against God."

"Forgiven" is aphiêmi, which means "to send forth," "to launch," "to send away," "to put away," "to get rid of," "to set free," and "to be released from." It means literally "to go from." It is interesting that this word gets translated as "forgiven." It is Christ's first word in the Gospel Mat 3:15) when he tells John to "suffer" baptizing him. It is often translated as "to leave" or "to let" in the Gospels. It is first translated as "forgive" in the Lord's Prayer (Mat 6:12) where it is applied to fogiving debts. It has the sense of leaving something alone and leaving someplace.

"Spirit" is pneuma, which means "blast," "wind," "breath," "the breath of life," and "divine inspiration."

The larger context here is still unity and the division between good and evil. Sin and speaking inappropriately are not enough to divide a person from the divine. Speaking against the spiritual and the divine is the real separation between good and evil.
