A sound analysis of a new metaphor follows a definite order:
1. Identify the established source meaning.
2. Identify the intended new target meaning.
3. State the precise common feature.
4. Classify all three as sensory or conceptual.
5. Explain the contextual clue preventing a literal reading.
Worked case: “ṭaghā al-māʾ” moves from rebellion to abundant water, with exceeding a limit as the relation. Without first distinguishing the source and target, one cannot tell the direction of the transfer.
