Syntax

Arguments (valence): say vs. tell

• Say requires a subject (S) and a direct object (COD), i.e. what is said. (ce qui est dit, ou ce qu'on dit)

• Boris didn't say anything.

• An optional indirect object (COI) (to whom it was said) is introduced with the operator/preposition "to".

• • Boris didn't say anything to Lily.

Tell requires a subject (S) and a indirect object (COI) (to whom it was said). to is not used to introduce the indirect object.
The direct object (COD), i.e. what is said (ce qui est dit, ou ce qu'on dit) is not required syntactically.
This direct object can be either a noun phrase (the answer, the truth, a lie, a story, ...) or an infinitival (to wait, to call back later... etc.)

• Boris didn't tell her.
