Forms
obrēpō (present infinitive obrēpere, perfect active obrēpsī, supine obrēptum); third conjugation[1] Some manuscripts spell it oprēpō, and a variant obripiō is found.[2][3]
Etymology
It is from Latin ob- + rēpō (“to creep”).[2][3] De Vaan traces rēpō to Proto-Italic *rēp-e/o- and Proto-Indo-European *h₁reh₁p- (“to creep”), or a root with long ⟨ē⟩, comparing Lithuanian rėplióti (“to creep”).[4]
Earliest recorded meaning
De Vaan dates it from Plautus.[4] In the OLD's quotation Plautus fears that death may creep up meanwhile.[2][5]
Semantic evolution
It is to creep up stealthily, so as to attack or surprise: Tibullus says he could creep in even at midnight.[2][6] Cicero's son writes of a man who often drops in on them unawares at dinner.[2] Figuratively it is to approach a task by stealth, as Terentianus Maurus does.[2] Of conditions it is to come on someone unawares, as death in Plautus.[2] It is also to slip past one's guard: Seneca shows where a question sneaks in.[2] Church Latin glosses it to take by surprise, creep upon, steal upon.[7]
