Platonic: 1. ĭdĕa (Gr. ιδέα): the i. is the eternal type, i. est exemplar aeternum, Sen. Ep. 58, 15: Macr. 1, 14, med. (Cic. uses the Gr. word). 2. spĕcies, ēi (appy. the current Latin equiv.): cf. Cic. Top. 7, init. (N.B.--Not to be used in gen. or abl. pl.: Cic. l. c.) 3. forma: cf. Cic. Top. l. c., formae sunt quas Graeci ἰδέας vocant: to be used rather than species in gen. and abl. pl. 4. exemplar, āris, n. (Gk. παράδειγμα): cf. Sen. Ep. 58, 15 (supr.). II. A conception, notion: 1. nōtio: nature has impressed upon the minds of all an i. of gods, in omnium animis deorum n. impressit natura, Cic. N. D. 1, 16, 43: v. notion. (For innate idea, v. innate.) 2. nōtĭtia (more definite than preced.): to have some i. of God, habere n. aliquam Dei, Cic. Leg. 1, 8, 24: v. notion. 3. spĕcies, ēi (like preced.): there dwelt in his mind an i. of eloquence, insidebat in ejus animo s. eloquentiae, Cic. Or. 5, 18: i.s inconsistent with the truth, s. aliae veris (al. veri), Hor. S. 2, 3, 208. 4. imāgo, ĭnis, f. (a kind of mental picture): my mind shrinks back from the i. of such a crime, norret animus tanti flagitii imagine, Tac.: even barbarians have some i. of justice present to their mind, justitiae barbaris quoque apparet aliqua i., Quint. 2, 20, 5. 5. informātio: v. conception (III., 2). Phr.: to form an i. of the nature of (a thing), intelligere et cogitatione complecti quale sit, Cic. Tusc. 1, 22, 51: you may form an i. how wearied out I am, concipere animo potes quam simus occupati, Plin. Ep. 3, 9, 24 (v. to conceive): not to be able to form the faintest i. of a thing, aliquid ne suspicione quidem attingere posse, Cic. N. D. 3, 25, 64. III. A thought: sententia (esp. when expressed in a concise form, a maxim): acute i.s, crowded together, acutae crebraeque s., Cic. de Or. 2, 8, fin.: cf. Plin. Ep. 1, 16, 2, adsunt (ei) aptae crebraeque sententiae. Sometimes res (matter) may serve: thus Cic. describes Thucydides as, ita creber rerum frequentiâ (so rich in ideas) ut verborum numerum sententiarum numero consequatur, de Or. 2, 13, 56. Phr.: association of i.s, *rerum cogitatarum (animo s. mente comprehensarum) inter se consociatio: the modes of association of i.s are numberless, *infinitis modis quae cogitamus inter se consociantur. (N.B.--By no means associatio idearum in philos. language, idea must be used only to represent the Platonic ἰδέα: v. supr.)
