Pronunciation

  • Classical: [ˈɫaːp.soː][1]
  • Ecclesiastical: [ˈlap.so][1]

Forms

lāpsō (present infinitive lāpsāre, perfect active lāpsāvī, supine lāpsātum); first conjugation, impersonal in the passive[1]

Etymology

It is from Latin lābor1 (“to slip, glide”), with the frequentative suffix -tō;[2] Wiktionary derives it from the perfect participle lāpsus.[1] According to the TLL, the deponent verb first gave a deponent frequentative lāpsor, whose present participle is the form Virgil uses, and Statius drew the active verb from that participle.[3]

Earliest recorded meaning

It first appears in Virgil (70–19 BC),[4] as a present participle, of someone slipping in a son's blood (in multo lapsantem sanguine nati).[5][3]

Semantic evolution

The finite active verb is first used by Statius, of a fighter tottering and falling from a wound.[3][5][6] Tacitus has horses slipping in their own blood and on the slippery ground of marshes,[5][6] Silius Italicus a tottering step,[5] Florus a man reeling from drunkenness and dizziness,[6] and Ammianus Marcellinus slipping feet.[5][6] Gellius uses it figuratively of words that are babbled out.[5][6] Glossaries explain it with forms of labi.[3] In manuscripts it is sometimes written with -bs- and confused with lasso.[3]
