Pulpamentum (and its shorter form pulmentum) are tidbits made from pulpa (meat): voltisne olivas, aut pulpamentum, aut capparim? Curc. 90; mihi est cubile terra, pulpamentum fames, T. 5, 90; primus ad cibum vocatur, primo pulmentum datur, M. G. 349; num ego pulmento utor magis unctiusculo? Pseud. 220.
Salsamenta are pickled fish (salsus) although once in Cicero the word in the singular means brine: salsamenta haec, Stephanio, fac macerentur, Adel. 380; de vino aut salsamento putes loqui quae evanescunt vetustate, Div. II, 117.
Sincipitamentum (Ritschl and Brix) is a comic word, with the same meaning as its noun stem, sinciput: iube opsonarier pernonidam aut sincipitamenta porcina, Men. 211; comedam, inquit, flebile nati sinciput elixi, Juv. 13, 85.
Atramentum is a liquid possessing the quality expressed by the adjective stem (ater); this context shows it to mean ink: calamo et atramento res agitur, Q. fr. II, 14, 1. In one example it means shoe blacking: pater accusatus a M. Antonio sutorio atramento absolutus putatur, Fam. IX, 21, 3. In one example also, it is used in speaking of fish: atramenti effusione sepiae se tutant, N. II, 127.
Scitamenta (scitus) are tidbits, dainties both literal and figurative: iube aliquid scitamentorum de foro opsonarier, Men. 209; ὁμοιοτέλευτα καὶ ὁμοιόπτωτα ceteraque huiusmodi scitamenta, Gell. 18, 8, 1.
Perhaps the variety of meaning of these analogical formations indicates that no single precise meaning had become attached to -mentum.
