A 'teaching the meaning of which is implicit, or has to be inferred' as contrasted with a 'teaching with an explicit or evident meaning' (nītattha-dhamma).

In A.I.60 (PTS) it is said: "Whoso declares a sutta with an implicit meaning as a sutta with explicit meaning (and conversely), such a one makes a false statement with regard to the Blessed One." - See paramattha.
