«فَإِذَا اتَّفَقَتَا»
When the two clauses agree.
The classification of clauses as statement or non-statement must consider communicative force as well as grammatical form. A sentence framed as a report may in context convey a command, prohibition, or prayer. Clauses with different forms can therefore share a functional meaning.
This establishes the distinction between agreement in both wording and meaning and agreement in meaning alone. The detailed scriptural examples belong to the following lesson.
This leads to eight broad possibilities: two in which the clauses agree in both form and function, and six in which agreement at the level of meaning coexists with a difference in formal classification.
