But after all, in these cases which I have cited one can see that this particle is lengthened because the letter n is dropped; for the loss of a letter is compensated by the lengthening of the syllable. This principle is observed also in the word cōgo; and it is no contradiction that we pronounce cŏegi short; for this form cannot be derived from cōgo without violation of the principle of analogy. For analogy in this sense of regularity, see ii. 25. Gellius thought that coegi was an irregular form because oē did not contract, as oi did in cogo; but contraction of unlike vowels did not take place when the second was long; cf. coāctus. Cicero's rule is correct, because a vowel is naturally long before ns and nf. The case of pro is quite different. The ō in cōpertus is due to contraction from co-opertus. Cōligatus is a very rare form; Skutsch, quoted by Hosius, thought it might come from co-alligatus. The ō in cogo is also due to contraction (co-ago, co-igo), which does not apply to the perfect coegi. Compensatory lengthening takes place usually when an s is lost, as in cōnecto for co-snecto, or n before s and f; less commonly when nc is lost before n.

That Phaedo the Socratic was a slave; and that several others also were of that condition.
