Choosing the right word Döderlein's Latin Synonyms

Lacuna · Lacus · Stagnum · Palus · Uligo · Lama · Lustrum

Lacuna denotes, in poetical language, any standing water, from a sea to a pool; lacus and stagnum are collections of standing water kept sound and fresh by their own springs, or by ebbing and flowing; lacus (liquere) is large enough to bring to mind the image of the open sea, in opp. to the main sea, like λίμνη; stagnum, like a pond, not so large as to resemble a lake, in opp. to a stream, like τέναγος; whereas palus and uligo are collections of standing water corrupted and grown foul; palus (πλυδᾶν) is, like a marsh, a district covered with a surface of foul water, like ἕλος; uligo (from ὀλός) like a moor, a district soaked through with foul water. The palus appears as a mass of water made thick by mud and bog-earth, in which a person may be drowned; uligo only as ground thoroughly soaked with water, in which a man may sink down. Lastly, lamæ and lustra denote standing waters of small extent; lama, a mere dirty and filthy puddle on a high road; lustra, an ill-smelling and noisome quagmire in woods, etc. (v. 30.)

Phrases from Meissner's Latin Phrase-Book

to complete the censorship (by certain formal purificatory ceremonies = lustro faciendo).

lustrum, i, n. 1. luo, lavo; cf.: monstrum, moneo,
I. a slough, bog, morass, puddle.
I. Lit.: prodigunt in lutosos limites ac lustra, ut volutentur in luto, Varr. R. R. 2, 4, 8.—

Curc. 4, 2, 22: in lustris latet, Turp. ap. Non. 333, 15: in lustris, popinis, alea, vino tempus aetatis omne consumpsisses, Cic. Phil. 13, 11, 24: homo emersus ex diuturnis tenebris lustrorum, id. Sest. 9, 20.—
2. Debauchery; cf.: lustra significant lacunas lutosas, quae sunt in silvis aprorum cubilia. A quā similitudine, hi, qui in locis abditis et sorditis ventri et gulae operam dant, dicuntur in lustris vitam agere, Paul. ex Fest. p. 120: domus, in qua lustra, libidines, luxuries, omnia denique inaudita vitia, versentur, Cic. Cael. 23, 57: studere lustris, Plaut. As. 5, 2, 17: lustris perire, Lucr. 4, 1136: vino lustrisque confectus, Cic. Phil. 2, 3, 6: qui pugnent, marcere Campana luxuria, vino et scortis omnibusque lustris per totam hiemem confectos, Liv. 23, 45, 3.
lustrum, i, n. 2. luo,
I. a purificatory sacrifice, expiatory offering, lustration, made by the censors for the whole people once in five years, after completing the census, and in which a swine, a sheep, and a bull were offered (suovetaurilia): lustrum condere, to make the lustral sacrifice: lustrum condidit et taurum immolavit, Cic. de Or. 2, 66, 268: censu perfecto edixit, ut omnes cives Romani in campo primā luce adessent. Ibi exercitum omnem suovetaurilibus lustravit: idque conditum lustrum appellatum, quia is censendo finis factus est, Liv. 1, 44; 3, 24; cf. id. 35, 9; 38, 36; 42, 10. The census could also be taken without being followed by a lustrum, Liv. 3, 22, 1; 24, 43, 4: sub lustrum censeri, at the close of the census, when the lustrum should begin: sub lustrum censeri, germani negotiatoris est (because these were usually not in Rome, and were included in the census last of all), Cic. Att. 1, 18, 8.—Being a religious ceremonial, the lustrum was sometimes omitted, when circumstances seemed to forbid it: census actus eo anno: lustrum propter Capitolium captum, consulem occisum, condi religiosum fuit, Liv. 3, 22, 1. Hence in part, doubtless, must be explained the small number of lustra actually celebrated; thus, A. U.

C. In gen., a period of several years; of four years (of the Julian calendar), Ov. F. 3, 163; cf. Plin. 2, 47, 47, § 122: ingens lustrum, the grand lustrum, a hundred years, at the end of which the ludi saeculares were celebrated, Mart. 4, 1, 7.—

Origins

Per De Vaan (2008), from Proto-Indo-European *l(H)u-(s)tro- (“dirty place”), from Proto-Indo-European *le(H)w- (the same root as lutum (“mud, dirt, clay”)) + *-trom (see -trum), compare lūstrum, flū̆stra and mōnstrum. Valpy (1828) proposed instead a borrowing, with change of *d to /l/, from Ancient Greek *δύστρον (*dústron), from δύω (dúō, “to plunge”).

Origins

From Old Latin *loustrom, of uncertain origin, with multiple theories proposed: * from Proto-Indo-European *lewkstrom, from *lewk- (“to make bright”) (whence lūceō), * or from Proto-Indo-European *lewh₃strom, from *lewh₃- (“to wash”) (whence lavō), * or from Proto-Indo-European *lewHstrom, from *lewH- (“to expiate, set free”) (whence luō). Compare lustrum, flū̆stra and mōnstrum.
