Datapoint Sri Lanka Portuguese/Complementizer with verbs of knowing
Comment on Value 1: The bare quotative complementizer falaa is best construed as a conjunctive participle (see Feature 72 "Nominal and verbal conjunction"), which, though expressed by the bare verb in Sri Lanka Portuguese, is a distinct form in Tamil and Sinhala. Both examples for Value 1 are indirect questions; no indirect statements appear in the corpus using falaa as a complementizer, but this reflects a limitation of the corpus rather than a grammatical constraint.
Comment on Value 2: The complementizer is the perfective participle of 'say'.
Comment on Value 3: The indefinite particle voo can be used as a complementizer in indirect questions in order to emphasize that the speaker has no idea.
noos oondi jaa-nasa voo deevs-pa mee saba
[1PL where PST-be.born INDF god-DAT FOC know]
'Where (the heck) we were born, God only knows.'
The "relative importance" indications are impressionistic rather than empirically based.
