Subordinate conjunctions can only introduce clauses or infinitives; they cannot relate
other syntactic constituents. There are different kinds of subordinate coordinations
with different
syntactic behaviour: the subordinate coordination `que' which introduces noun clauses,
subordinate coordinations which introduce subordinate interrogative sentences (e.g. `quand') and subordinate coordinations which
introduce sentences (e.g. `parce que').
Test:
Given X a conjunction: If the second occurrence of X can be replaced
by `que', then X is a subordinate conjunction.
Examples:
- Comme / il est tard et qu'il a faim, il est rentré.
- Après qu' / il a préparé le repas et
qu'il a mis la table, ...

Test:
