Lachmann's lawn.

Brit.

/ˈlaxmənz ˌlɔː/, U.S.

/ˈlæxmənz ˌlɔ/,

/ˈlæxmənz ˌlɑ/

Origin: From a proper name, combined with an English element. Etymons: proper name Lachmann , law n.¹

Etymology: < the genitive of the name of Karl Lachmann (1793–1851), German philologist + law n.¹ Compare German Lachmannsches Gesetz (1882 or earlier).Lachmann formulated the rule in 1850; compare:1850 K. Lachmann Libros Commentarius i. 54 in Lucretius De Rerum Natura Libri Sex Participia passiva ea quorum in praesenti consonans est aut liquida aut s semivocalis, quantitatem praesentis secuntur..contra ubi in praesenti media est, participia producuntur [those passive participles whose consonant in the present is either a liquid or the semivowel s, follow the quantity of the present; whereas when the consonant in the present is voiced, the participles are lengthened].

The rule that, in Latin, a short root vowel in the present tense stem of a verb typically corresponds to a long vowel in the past participle if the present tense stem ends in a voiced plosive.The processes which gave rise to this pattern, the date of their occurrence, and the nature of their interaction with other phonological or morphological processes are all disputed.
