Just in case there’s any doubt as to what constitutes the Liturgy of the Word at Mass:
11. “Readings from Sacred Scripture and the chants between the readings form the main part of the liturgy of the word. The homily, the profession of faith, and the universal prayer or prayer of the faithful carry it forward and conclude it.” [old GIRM 33]
In the US edition of the new GIRM, you can read the rundown here, beginning with section 55.
