Theory of Sets, chapter I, Appendix 0. Characterization of terms and relations

If $A_1$ , $A_2$ , ..., $A_p$ are $p$ significant words and if $f$ is a sign of weight $p$ , then the word $f A_1 A_2 \ldots A_p$ is significant.

Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
