Fricare, see [Lævis].
[Frigere]; Algere; Algidus; Alsus; Gelidus; Frigus; Gelu; Glacies. Frigere (φρίξαι) means to be cold, in opp. to calere, Cic. Fam. viii. 8. Auct. Her. iv. 15. Sen. Ir. ii. 18; whereas algere (ἀλγεῖν) means to feel cold, in opp. to æstuare. Cic. Tusc. ii. 14, 34. Sen. Ir. iii. 12. Plin. H. N. xvii. 26. 2. Algidus denotes cold, as an unpleasant chill; alsus, as a refreshing coolness. 3. Frigidus denotes a moderate degree of coldness, in opp. to calidus; whereas gelidus means on the point of freezing, in opp. to fervidus. 4. Frigus denotes, objectively, cold in itself, which attacks a man, and leaves him; whereas frigedo denotes cold, subjectively, as the state of a man attacked by cold, which begins and ends; it is an antiquated word which has become obsolete by the general use of frigus. 5. Gelu, gelus, gelum, (γλοία) denote, like κρύος, cold that produces ice; gelicidium, like κρυμός, a single attack of frost, a frosty night; and glacies, like κρύσταλλος, its effect, ice. (iii. 89.)

[Frustra]; Nequidquam; Incassum; Irritus. 1. Frustra (from ψύθος) means in vain, with reference to the subject, whose expectation and calculations have been disappointed; whereas nequidquam (that is, in nequidquam, in nihil), to no purpose, refers to the nullity in which the thing has ended. 2. Hence frustra, used adjectively, refers to the person; whereas irritus, the actual adjective, refers to the thing. 3. Frustra and nequidquam denote merely a failure, without imputing a fault, like μάτην; whereas incassum involves the accessory notion of a want of consideration, by which the failure might have been calculated upon, and foreseen, as in attempting any thing manifestly or proverbially impossible, εἴς κενόν. (iii. 100.)
