The verbs used with medicamen and medicamentum show a lack of differentiation between these nouns: quod diceres te violentis quibusdam medicaminibus solere _curari_, Pis. 6, 13; si eo medicamento _sanus factus_ esset, Off. 3, 92. The verbs with molimen and molimentum in the following examples are very similar, and there is the same adjective modifying each noun: temptat _revellere_ annosam pinum _magno_ molimine, Ov. M. 12, 357; neque exercitum sine _magno_ commeatu atque molimento in unum locum _contrahere_ posse, B. G. I, 34, 3. Identity of verbs and the case of momen and momentum show there is no difference in their meaning: momine uti _parvo_ possint _impulsa_ moveri, Lucr. 3, 188; animus _paulo_ momento huc vel illuc _impellitur_, And. 266. Parallel instances of blanditia and blandimenta are seen in these examples: haec _meretrix_ meum erum sua blanditia intulit in pauperiem, Truc. 572; illum spero immutari potest blandimentis, oramentis, ceteris _meretriciis_, Truc. 318; _benevolentiam_ civium blanditiis et adsentando _colligere_ turpe est, Lael. 61; Lepida blandimentis ac largitionibus iuvenilem _animum devinciebat_, Tac. H. 13, 13. Adiutorium is a rare word, but in the following examples it is seen to have the same general meaning as adiumentum, “help”: sine adiutorio _ignis_ nihil calidum est, Sen. Ep. 31; neque apud homines res est ulla difficilior neque quae plura adiumenta _doctrinae_ desideret, De Or. III, 84. Experimentum in the plural naturally means the same as experientia (experience), but in the singular also they both mean a trial or attempt, or the result of trial, proof: debemus _temptare_ experientia quaedam, sequentes non aleam, sed rationem aliquam, Varro, R. R. 1, 18, 8; hoc est maximum experimentum, _hanc vim_ esse non in die positam sed in cogitatione diuturna, T. 3, 74. With the meaning of experience: Agrippa non _aetate_ neque _rerum_ experientia tantae moli par, Tac. A. 1, 4; Metello experimentis _cognitum erat_, genus Numidarum infidum esse, Sall. Jug. 40, 3. Firmamen and firmamentum might be interchanged, in both their figurative and literal meanings: ruptosque obliqua per ungues porrigitur _radix_, longi firmamina _trunci_, Ov. M. 10, 491; _ossa nervique_, firmamenta totius _corporis_, Sen. De Ira, 2, 1, 2. Both the dependent genitives above express concrete objects; in the following they express abstract objects: unicum lapsae _domus_ firmamen, unum lumen afflicto malis temet reserva, Sen. Herc. Fur. 1251; sic ille annus duo firmamenta _rei publicae_ per me unum constituta evertit, Att. I, 18, 3. Documen occurs only once, but its context shows it to be equivalent in meaning to documentum, which is used in strikingly similar contexts: flammas ut fulguris halent pectore perfixo, documen _mortalibus acre_, Lucr. 6, 391; ut sint reliquis documento et magnitudine _poenae perterreant_ alios, B. G. 7, 4, 10.
