What is the meaning of 'two truths' in the Manorathapūraṇī?

In the Manorathapūraṇī (a later-day commentary), it is written: > *duve saccāni akkhāsi sambuddho vadataṃ varo sammutiṃ paramatthañca tatiyaṃ nupalabbhati* > > *The Awakened One, best of speakers, Spoke two kinds of truths: The conventional and the ultimate. A third truth does not obtain.* > > *tattha: saṅketavacanaṃ saccaṃ lokasammutikāraṇaṃ paramatthavacanaṃ saccaṃ dhammānaṃ tathalakkhaṇan ti* > > *Therein: The speech wherewith the world converses is true On account of its being agreed upon by the world. The speech which describes what > is ultimate is also true, Through characterizing dhammas as they > really are.* > > *tasmā vohārakusalassa lokanāthassa satthuno sammutiṃ voharantassa musāvādo na jāyatī ti* > > *Therefore, being skilled in common usage, False speech does not arise in the Teacher, Who is Lord of the World, When he speaks according to > conventions.* > > *(Mn. i. 95)* Is this saying worldly people understand dhamma different to enlightened people & that worldly people do not understand dhammas as they really are but only how they imagine them to be?
