Faa sometimes links a second statement to the first as an effect or consequence. Yet not every faa by itself conclusively proves a comprehensive causal relationship. Its sequential force must be read along with the subject and context.
For instance, “Clouds gathered, so rain fell” suggests a connected occurrence and may convey causality in context; the particle alone does not establish every aspect of the causal explanation.
In legal theory distinguish the sequence of mention from the legal ground of a ruling, especially when an entitlement or consequence is attributed to a prior act.
